I'd very much like to see the alignment procedure - if you know anything about the references they used for alignment at the time? that'd be great to learn about!
@ 54:44 ... PHOTO DETECTOR ? {another}
Am curious about exact spacing between red alignment marks ?
I was scratching my head over a schematic for a Silvertone 1831 radio that listed the resistance in M. I was assuming it was meg. The schematic on closer inspection listed the Meg-Ohm resistance as MG for meg and M for K, thank you very much for these videos. My 2 cents, I enjoy the 2 hr videos more than any of the superhero movies out right now or televised sports games out there and walk away feeling more educated.
@@mrbyamile6973 Same, prefer 2 hour vids tbh
I'm absolutely delighted to have found your channel. I'm an old guy who trained in electronics test and inspection some 50 years ago although unfortunately, for various reasons, I haven't used those skills for many years. Watching your amazing presentations, I realise how refreshing and rewarding my early introduction to electronics would have been if I'd had someone even close to your level of incredibly capable and dedicated enthusiasm as my tutor. I'm privileged to be able to watch the results of a man with a clear analytical mind coupled with compelling presentation. I will watch all of your videos'. Very grateful thanks for what you do.
Same here. I learned my vacuum tube electronics 50 years ago and have very little need to use since. Watching Mr. Carson is being back memories that I learned back then.
9 months of work well done now you have the only one in the world that still works fantastic
You are probably right, this is "most likely" the only one in existence that works properly.
most anticipated sequel of 2019!
It’s literally the rocky balboa of electronics device cinema
The mystery device is a neon tuning indicator. A variable voltage applied to the control electrode will give a glowing orange bar of variable length.
The solid state tube replacements were widely used by the telephone industry for updating carrier telephone gear. The Bell System/Western Electric name for them was a "HIN" or Hybrid Integrated Network.
Agreed. If I were to guess a typenumber, I'd hazard an IN-13, as those seem to be the most widespread of these devices nowadays and has the matching 3 wires.
Bob Weiss Someone deserves a cookie!
The tube replacement things, well then i save them, i was thinking Ericson/Bombardier code plug in for railway ATC balises...
I remember Heath company sell Solid state tube replacements to be used in their IM-18, IM-28 and similar vtvm that uses the 12AU7 and 6AL5 vacuum tubes.
Your skills, patience and ability to explain theory and practice are simply marvelous. It is also surprising how accurate the Vedolyzer was without the touch up alignment. Well done sir...well done.
His intelligence, above 130?
Yea, he isnt average. Thats for sure.
I am 78 years of age and have been a amateur radio operator since I was 19 years of age.
My eyesight is also 78, in other words bloody horrible. I am replacing my modern equipment
with older valve equipment. Why ??, Not because I don't like my modern equipment, but because I no longer can see surface mounted components and so cannot repair it.
Vintage equipment is also a bit harder but I can cope with a magnifying glass.
What is the reason I tell you this ??. Well I really enjoy your video's on equipment that is older and utilises point to point wiring. Don't get me wrong, I understand modern devices, I don't understand why they have to look like micro organisms and you have to identify them using a electron microscope.
Such is progress and old men like me are defunct. The king is dead, long live the king.
You are the best tech I have come across by a long way.
I look forward to many more video's.
Best regards from " Down Under "
Michel vk3kvw
well, i'm 42 and also need my 20x microscope to solder smd sizes under 1206 (0.12 in x 0.06 in), I mean you should not feel too old for that inconvenience :)
I am also 78 years of age and an amateur radio operator (KQ2E). I just can't SEND CW like I used to do it... every day and every way. BUT, now I have a new rig (Icom 7300) with a "new fangled" micro-something that I can TALK into! ROFL Honestly? I'm THRILLED to see old equipment being utilized again for modern equipment as many people think you need a zillion dollar MSO scope and a counter which counts to 200 GHz. Oh yeah... a DMM which reads to a picovolt. Yeah. Like, come ON now!
Hi Odium
I tried to work with these microscopely small components But every time I try to pickup one with a pair of tweezers The damn thing jumps all over the place. Are you sure they are not alive. I am not so sure. Perhaps it got something to do with my hands. The bloody things won't stay in one place.
Oh to be 20 again.
Michel vk3kvw
hahaha i am 14 years old and i love electronics (but i am new to it) and im exactly the same i always go for old stuff like old Tektronix scopes and old radios just because i like old stuff plus its easier to repair
@@goofyahhuncleproductions42069 as I am about that age and share those interests, I can relate
I'm so glad this old hunk of scrap made it to one of the very few people, like yourself, who have the wherewithal and skill to bring it back from the dead! And thanks all the more for allowing us all to see it happen.
Really great to se this piece of test gear back up and running. You di a outstanding job with this one. If not one of your best. I also think it was very noble to mention Don and his channel. He is a great guy and does a fantastic job on his restorations. Thanks for sharing Paul.
Thanks for your kind comment Buddy!
Kinda funny when he was mentioning the hack job on the veri-resistors...I was thinking Buddy could fix them, he's awesome restorations and stuff like that! :) ~Jack, VEG
Do not fall for the siren calls of "modern" UA-cam, long videos and good explanations are what got most if not all of us, here.
The 4 C. Clarity in thought clarity in speech clarity in workmanship clarity in electronics you are the master Tech ...
Thank you for sharing your knowledge and skills. I have no technical background; it's your enthusiasm and rigour that holds me captive. Dee, London.
I agree, I'm not a whiz so hanging on your every word to understand things clearly is a huge benefit and your calm articulate manner really is so awesome that binge watching and taking notes is a breeze lol.
I am constantly in awe of your ability to re-sculpt an original design into a modern work of art -- that works! Your topography is second to none.
Thanks for your kind words John!
my dad, a hard core civil engineer, made DARN SURE that I always proceeded a decimal point with a leading zero, a k.a 0.312 rather than .312. A valuable method TODAY!
Absolutely incredible job! Don't shy away from 3 hour videos if you can find time to film and edit them
Hey Paul, you had mentioned if we wanted to see you do an alignment on this piece, let you know. It would be a shame to have gone through all you have done so far and not finish it with an alignment. The cherry on top of the sundae would this alignment be! I vote for it! I’m probably not alone in that. This has been a very detailed and laborious project for you. You got some very appreciated help! Very fine video!👍🏻
Once again, you have outdone yourself. I got the alert on my phone, but I had to wait 2 days until I could sit down and watch it on my 55in flat screen in crystal clear HD and I am so glad I did. You really get a sense of how much work and attention to detail goes into this type of restoration and no one does it better than you. Outstanding. And YES on the alignment!
Excellent series on the Vedolyzer, Mr Carlson! I waited and watched the whole trilogy tonight. Your thoroughness and forethought on these electronic subjects is amazing! Very enjoyable watching a true professional at work.
Been looking forward to this one, Paul. You didn't disappoint, that's a fantastic piece of gear you have, and I dare say it now runs better than the day it was built. Do keep up the in-depth videos and pay no attention to the ADHD crowd. They can always fast-forward if they get bored, but you can't put back that which wasn't there to begin with. That's what separates you from the rest of UA-cam. You put back the detail and make electronics interesting again. Congrats on another fine restoration!
As I actually have adhd, I do fast forward through the video (bad habit I’m trying to stop) but I do agree
That is an awesome device/tool! The components aging is not a design fault. Thank you for doing all that hard work replacing what needed replacing/cleaning/fixing and taking us along on the journey. 1939?! Wow. Back when electronics were made to last.
What an incredible piece of equipment Mr. Carlson! Probably the first commercially successful multi-analyzer. Can't wait to see this in use on future projects both on YT and your Patreon page at your vintage workbench. Please show the alignment procedure. Very nice restoration indeed! Thank you for what you do!
Yes, I agree with most here! DO NOT SHORTEN your videos! With the awesome level of knowledge and wisdom you have teaching this stuff, it would be silly to shorten. If someone really cares and wants to learn, they will watch, and complain that a 3 hour video is too short! If not, then I'm sure they can find other stuff that is more interesting to them, to watch. 73 Michael KE4EST
It's been a few years, but I must agree. The Only thing missing here is the smell. Warm tubes, rosin, Bakelite, and the cigarettes in the ashtray, plus coffee.
These are find memories of my childhood. I had a friend, a ham, that my father introduced me to. My father was an engineer, and he supported my love of electronics.
This was in the late 60s. Yes.
I do love watching these restorations.
73.
Great rebuild; I do enjoy these videos very much, yours is the only channel I have ever joined the Patrion with, and that says a lot since in my ever so long life, I have been a Soldier, Police Officer (licensed in 2 States) EMT (National Registry), Carpenter, Wood worker, Business Office Manager, Gun Smith (degree), TV Repair Guy, Paralegal (Degree) Computer guy (for a small town with no service for 12 years) and general-fix-it guy most of my life. Now I am mostly a Nomad, my good wife of 50 years (This Month!) have a 36 foot Class A Motor Home which we use to tour these United States when our presence is not needed at our home Sticks and Bricks local (Where we are now, family illnesses have parked our RV for about a year now as my aged relatives are passing on.)
Happy 50th Jerry!
Thanks for all the interesting video's Mr. C. I love this stuff! Every time I watch you I learn at least a little something I didn't know before, or at least refreshes my memory from long ago. Love your Patreon channel too. Long video's, yes! Trivia, yes! Alignment on the Vedolyzer, yes!
Outstanding work and I really enjoyed your video. Would love to see the alignment procedure.
Paul, this hits me at 17:15 PM and those are great news! I watch it later in the evening, but I wonder if "Vedolyzer" can be used in the future to express the amount of effort of how an future or past restoration compares to this :) Many Thanks for sharing and doing this all for free Paul, that's an huge amount of effort!
Thank You Ralf for your kind comment!
Ralf you didn't take a guess at the "mystery item" I was willing to bet you would have I.D. it already. lol
I'd guess most projects will be the half to quarter vedolyzer range of effort, 9 months is a long time
Hello i had seen this series when you first posted it and came back to watch it, as i had wandered off into a different direction. I sold my beloved restored German Grundig 1950s AM, FM, SW w/4 speed turntable and was in a bit of withdrawal. I was immediately calmed by your professor voice and terrific explanations. Your talents and gifts are very well shared and most appreciated. I hope all is well and I will be watching more often. I did complete a self tuning smoke generator for Model Train steam engine so i have been using my 70 year old brain, but alas not the big old radios and hot Tubes. This series was an excellent save and wonderful result, one of your best projects. Stay well, Dennis
I just watched all 3 parts of Vedolyzer during Laptop motherboard repair. Your voice is tranquillizing. My work goes much well with your videos in the same time :)
I'm perfectionist as well, but you are the best one.
So much work and precision you gave to that Vedolyzer.
You are awesome.
Paul - @43:07 one of the most rewarding observations to see all of your hard work and dedication pay off. An excellent job as always and I truly appreciate the mention in the beginning of your video; my subscriber count has since jumped. Thanks again for sharing your brilliant knowledge and skills with all of us. All the best. Don
No Problems Don, you have a great channel!
Absolutely loved this series restoration. I wish they still made equipment like this as well as to this standard. Absolutely amazing to see it so well calibrated after all that work done on it. I was absolutely expecting it to be almost completely out.
Been waiting for this Mr Carlson.
Lol at the random cap sitting on the table all alone.
Great video as always Paul
Ahh. Now we learn some key reasons why this wasn’t just another typical triumph for Mr C. Not to mention just when you thought you forgot about this cliff hanger.
Here it is. Posted. ? Yessir!!
Now we get to watch all three to put the whole story together.
Ya Paul. Looking forward to seeing this used on modern and less modern stuff.
That’s one of the main mandates of your lab. Will be very cool.
This a IN13 soviet nixie tube. Got 25 of them and I plan to make a very neat audio spectrum analyser
Congrats on the successful completion of the Vedolyzer refurb! I'd be happy to watch the calibration. For that matter, I'd be happy to watch anything you post, so long as it's even vaguely electronics-related. You're one of exactly 3 UA-cam subscriptions I've hit the notification bell for.
Amazing, this Vedolyzer, and its restoration. Beautifully done. Yes, would love to see the alignment procedure (and maybe a repair using it?). Those tube replacements are interesting devices too. Thanks for sharing all this!
Paul, you're my new hero! The attention to detail in your restorations/work are just short of phenomenal ! PLEASE keep making your videos, I'm trying to get back into electronics after leaving it back in the 80's. I never got as far into it as I wanted to back then, well, because kids and family needed fed and clothed, and there wasn't much money in it. LOL! Had to have a regular job to pay the bills. Now that I'm older, I want to get back into it. I have MUCH to learn/relearn, but some things are coming back while watching your videos. There's one thing I learned in this video especially, I DO NOT recall schematics using 'M' for 'K'. GOOD to know, thanks! :) I have some old radios I've just recently acquired to get started on, and I've purchased some test equipment. PLEASE keep up the great work and videos! :) :) When my situation gets better, I'll be jumping on Patreon for some more of your lessons. :) Thanks again! :)
Awesome. You set the standard for quality troubleshooting and you give me the confidence to achieve it myself.
Glad to help Rick!
i was told by an employee of textronix that every piece gets a bath when it comes in for service. soaked rinsed and dried before any service done.
you are 1000% correct about the power of wd-40 it cleans connections and protects them
pc ram sockets love it
That Is a Amazing Machine, VTVM and a scope, for Aligning a radio, all in 1 machine, setting the voltage, unreal ,You don't need anything else. when aligning a radio, Great Restore, great work, Great Machine, God Bless
Don's channel (Restore Old Radios) is one of my favorites.
I love the Vedolyzer! And this channel!
Truly inspirational. Truly superb. Steve Cornwall UK.
I really enjoyed this restoration. The old vintage test equipment is just sexy. I’m sure that they can make a piece of equipment that will do everything that this one could do but be the size of a transistor radio. I would rather have the vintage equipment because it connects us to the past. It’s hard to conceive that 50 years ago this month that they sent men to the moon using some vintage equipment we buy as antiques today.
There are electrical engineers that passed and maybe found a job- and there are good electrical engineers that found a job and made a diffrence for the company. I think we all know which class Mr. Carlson belongs too. That company was lucky to have his commission.
I definitely want to see a full alignment of this beast. I also think you challenged yourself to make an accurate graticule for the CRT.
The tube is a level indicator IN-13.
I'd like to see you calibrate it.... That's my favorite part. :)
Then install Linux on it :p
What a great find - beautiful piece of equipment! May have been lots of work, but what a great job you've done, and the alignment already very close - even after the hosedown. It must have been very satisfying to see that result. Please do not stop doing what you're doing, sir. I'm having fun watching and learning loads! Thank you. YES... please show us your alignment.
Beautiful restoration. I always learn something watching your videos keep them coming. I recently restored a Leader LBO-524 scope. I replaced all electrolytic capacitors and to my surprise I discovered five broken pcbs with broken traces, thankfully I was completely successful.
I like the long format and I watch them intently trying to learn, pause and re watch portions that exceed my grasp. I would enjoy the alignment process as well. THANK-YOU Mr. Carlson!!!!!!!
Thanks Paul! Nice work! I wouldn't mind watching the Vedolyzer alignment. I am glad that it turned out so well!
A one hour video on electronics has never gone by so fast. Perhaps Paul should refer to this restoration as his Supreme. It certainly seems that way to me.
Thanks for another great informative video. I always learn something when I watch these and that's a good job done on the much anticipated completion of the Vedolyzer.
Hi Paul, great job as always.
Been waiting for this for a long time.
Keep posting your fantastic videos.
Usually I'm not a fan of videos longer than around 10 minutes because many channels just pad out time unnecessary but when you release a new one I know it's gonna be a good show. Really you do such a great job overall that a 10 minute video would not cover everything in depth. Keep the length of you videos related to the topic at hand. If it needs to be 5 minutes, so be it. If it needs to be 60+ minutes, go for it.
Excellent work, knowledge and craftmanship, Mr Carlson. Best wishes from Sweden.
Well done!! All those weeks of hard work realy paid off!!! The fact it is so close to callibration is a sign that it was well designed in the first place. Congratulations on brining this piece of history to life! Of course we want to see you callibrate it fully!!!!
What a fascinating series. I like the way you employ such neatness and make point to point wiring look like a three dimensional PCP. Looking forward to seeing it used. Cheers. Oh, yes, happy to seem more of the actual work being done if possible.
Nothing beats the smell of old tubes..
At the World Radio History site, I found a number of nice large advertisements in issues of Radio-Craft magazine. July 1939 had the model 504 Vedolyzer (simpler, no scope). The May 1940 issue has the 504 but also has the 560 Vedolyzer (with the scope) and also the 562 Audolyzer. The January 1941 ad, unlike the other ads with photos, has a drawing of the 560-A Vedolyzer with drawings of various waveforms with big text at the top of the ad saying, "SEE The Signal". The end of the ad says, "...an instrument for COMPLETE DYNAMIC ANALYSIS." The ad mentions their 1941 catalog so it is likely some old catalogs exist somewhere. The company was located in Greenwood, Mississippi. These advertisements make very entertaining reading. A 1946 catalog was sold on eBay but it no longer had the Vedolyzer but did have a scope, many tube testers, audio generator, and meters and said it was their 20th year. So, it was founded circa 1926.
Paul, thank you so very much for this update on the Vedolyzer! I can only imagine the frustration, pain, irritation, and aggravation you went through to bring this wonderful series of videos to us! I am sure that a lot of "off air" time working on this was filled with "Blue Blazes" , but you stuck with it and brought us a wonderful education and treat. Please do the alignment for us, it might only be a "touch up" since it is so close, but would love to know what is involved in the alignment procedure on this particular device.
Amazing and beautifully done Sir. To bring the old girl back to life and be so close to spec is exactly what I'd expect from you. If I have equipment that needs work you are exactly the man I'd come to.
I am a complete and utter Neanderthal in relation to electronics, any diagrams shown, simply look like hieroglyphics to my brain.
Yet, the more I watch your uploads in their entirety, I come away a little more knowledgeable with the subject matter.
Thank you for your clear breakdown and efforts, look forward to future material sir.
You're welcome John!
You've put a lot of work into this unit, and I'd love to see it in operation! Which means a proper alignment, which I'd like to see.
Thank you, Paul, for all the long, hard work you put into these old units. I love seeing these venerable items realize a second life!
Wow, thanks Paul for this 3-part video on your exhaustive restoration of this premium piece of test equipment! I have never come across this particular instrument before but, I'll bet it was the "Cat's Meow" in it's day. It's nice you were able to find some good documentation on this equipment. When I would pick up old radios/TVs at the dump in the early 1970's to bring back to life, working out of the house as a teenager, I generally had no documentation so, any fix was more of a reverse-engineering effort.
I have only come across a very few old schematics during my life that used "M" for "k" on the resistor values. That's got to be very confusing for Newbies.
On the vertical amplifier design, you'll notice the plate circuits are very heavily loaded with relatively low resistor values plus, some series coils. The plate resistance of pentodes is very high compared to the grid 1 and plate capacitance to ground, which very much limits high frequency response. By using the low value plate resistors, the designers were throwing away gain (swamping out the electrode capacitance) to achieve high frequency response. This is why they used so many stages of apparent amplification. By looking at the circuit values used, I suspect the bandwidth is a few MHz! Most oscilloscopes in that day had a bandwidth of 100 kHz or less.
That dual-ganged variable resistor that was modified with the 2 drill holes, I wonder if that was a factory authorized service bulletin, it looked too clean for a Tech trying to hack out a quick fix.
I suspect the designers opted for using the flashlight batteries for the bias supply in order to get the cleanest possible DC voltage. The drawback however: since they are using sharp cutoff pentodes, the plate current will skyrocket if the -3 volt supply drops below -2 volts. Since they don't have a way to check the battery voltage from the front panel, you could easily cook your 1852/6AC7 tubes and possibly a plate resistor. I'm not sure what the carbon/zinc battery life would be inside that chassis with all those tubes generating heat, obviously shelf life at elevated temperatures. Cool stuff, keep up the good work!
Thanks for taking the time to write Bill, you know your stuff!
Impressive! The Tech, Paul's work, all of it!
Absolutely love your videos, very informative and fun to watch!
Amazing! Simply amazing!
And I don't give that statement very often on UA-cam. But you deserve it . So much.
i started out in electrical / electronics work and was gonna be an apprentice cnc repair guy...but i got offered computing, and i went with it...but i never really ever enjoyed computers...and 20 years later im kind of out of it ...but i still love electronics...maybe i should have stayed with electronics...its my true hearts desire.
Glad to see the Vedolyzer up and running. Nice job!
Thanks for focusing on 1930s electronics!
You're welcome!
I love every minute of each of your videos. Cheers!
I was going to joke and suggest "krytons". Hehe. No trifoil logo visible. I remember seeing these replacement devices years ago.
You restored the Vedolyzer far beyond my expectations. Looks like Tektonix quality, that rebuild of the vertical amplifier is...well..supreme.
Thanks for the completion of the project. The outcome was spectacular both in terms of work quality and instrument function. I personally wont need the alignment part. However, if it eventually will be published I surely will view it. (As every single video on this channel).
Absolutely amazing restoration job! First class work from start to finish.
And for what it's worth, I like the long-form content - The longer the better. I guess if you're looking for the sweet spot I guess around the 1 hour mark is good, though I could happily watch this stuff all day :)
An outstanding restoration of a brilliant device with an astonishing name!
I must say that I thought the name was even better before I learned that "Supreme" was merely the brand name. More hyperbolic adjectives in product names, please!
I am amazed at the quality (readability) of the schematics you have found. It would be really nice if modern on-line scan and publish for elderly IC's were so pristine - as they so often are not.
Nothing short of AMAZING, yes I just had to put that in all-caps :D Thanks so much Paul. I love it
Just quickly scanned the Supreme instructions on "A new system of Dynamic Analysis" (a pdf on Steve Johnson's site) which is chock full of basic instruction of radios and analysis of signals. I am sure you realize that essentially the Vedolyzer is the early precedent for the Spectrum Analyzer. You being the "Tracking Generator" you can follow the signal on the wave meter as you adjust the IF along the frequency. A step above the VTVM method of alignment. I need to thoroughly internalize this document,. I can see why you wanted this equipment working as instructional for us. Albert
Thanks for your kind comment Albert!
The M used on this vintage schematic is based on the Roman numeral M (M = 1000).
John , Yup... but it's still a bugger of a term to interpret for many younger readers.
I'm a Machinist I'm only 38 years old but I've been machining since I've been 7 years old. Right when cnc was considered voodoo or something that took millions of dollars of know-how to operate. It's funny how lazy and stupid a few smart people have made the masses. Yet people like Mr. Carlson keeps it old school and I respect and honer him. People lose sight of where why and how things came to be. But he knows , dam right he knows!
This is an incredible restoration. Mr. Carlson proves definitively his amazing engineering skills and artistic design. incidentally, I do love the long explanations. I follow these builds intently.
That is sick!!! so outer limits. Awesome restore. I commend you, not only for your knowledge and skill, but for your patience in going in there and restoring it. Its so awesomely vintage sci-fi ish, a fine exame from days of -izer everything.
This is the second video in a row I've watched on UA-cam today using WD-40 as a cleaner. The prior video I watched was from Mustie1, using it to coat a bike he was working on.
Yes! Let's see the alignment. Excellent video, as usual. Keep them coming.
Hello Mr C. I really enjoyed the vedo restoration and commentary. I’d like to see an alignment.
Yes, running @ 1.75x helps to move this along without losing the nuggets that are placed within Paul's restoration techniques.
Very impressive restoration. Exceptional workmanship!
Well worth the wait Paul,thank you so much again. The longer the video the better for me personally. Please do show the alignment as soon as possible.Can hardly wait! You have the patience of Job.and then some.
That was such an interesting and exhilarating video to watch Paul.. You're nothing short of a genius. Looking forward to the alignment of the Vedolyzer which is 10 years older than me 🤣..
Interesting that I follow you Paul and ALSO have been following Don for quite some time now. Both are excellent channels.
Thank you so much. Your attention to details make of you a great teacher. I look forward to follow your next project.
Back in TV repair days, I could build a multiple pot stack. Just pick each value you needed and stack them. I remember 3 different pots in a stack somewhere. Maybe a Halicrafters rig
.
I want longer videos.
I'm interested in learning this awesome stuff.
I would love to see the touch up alignment procedure, Mr C! Really enjoyed this video. I always learn so much each time I "tune in." Keep it up.
What an awesome piece of test gear! I look forward to the alignment video! Thanks for the top notch content!
Way cool....it lives....excellent work as usual Paul....keep em coming!!!
Great job with the Vedolizer, and all your videos, I concur with the other viewers that recommend NOT to shorten the videos, I can't get enough of your teaching skills and electronics knowledge. Thanks for taking the time, congratulations, and yes I would like to see the alignment procedure
We have come this far, I think seeing the alignment would be an awesome closing to this resto.
Congrats on finishing the Vedolyzer! An amazing work accomplishment. I claim Don as a mentor also, second to you of course. Albert
Once again this man has fantastic quality video and audio!
