I always chuckle when I open one of your videos and i see you sitting in front of all you equipment and i cant help but think that you are the final boss of electronics!
This guy charges a couple of bucks a month for a fantastic course. It’s an amazing deal. Please support him…. I would also like to add, that I am completely thick … yet some how or other I manage to follow the builds… you are learning something practical and even an idiot like me has fixed stuff and friends stuff. I don’t understand the maths very well but I have learned how to look at a circuit and work out what is doing what
I liked the fact that you laced the wire looms. I haven't done that in years. It's pretty much a lost art. I personally think lacing looks much better than cable ties.
Great result Paul, looks like something from a high end audio store. Thought I'd say thanks - been following your channel (and Patreon) for a few years now. You always have nuggets of new information in your videos (for me here it was the insulated screws for the transformers, and your metalbashing 101 intro ;) ). It's always nice seeing old kit brought back to life, especially when glowing tubes are involved - they do create that special ambience! Thanks Paul!
@@Drew_Snydermann I'll go along with you. In fact, blade type screws are entirely horrible, and Phillips are the only way to go. And don't bother lining them up!
We used a lot of that wax cord when I was in USAF electronics maint. The paint finish looks awesome. Only thing missing was turning the lights low so we could see those tubes in all their glory!
Wrinkle paint used to be easy to find in the home improvement stores. It has in recent years disappeared from the paint department. Thanks for giving me a brand name to search for. This paint also works well for restoration of old units that are faded and dirty. Thanks
Your design sensibilty/practice lends an aura of authenticity to your builds that should be the envy of any maker. Hollywood should call you when era-specific props of the radio sort are needed.
Paul -- Your power supply is an absolute gem! What a wonderful project! You asked if we thought it would be worth restoring the face plate of the BC-348 to match, and I certainly agree! I can't wait to see how the '348 works with its brand new power supply! Thanks for another amazing video! 73 de Larry, K3LT
A lot of fun.....how about a lot of work! I don't know if it's OCD or just pure professionalism but Mr. C puts the "P" in perfect. I continuously learn something new watching this channel, a wealth of knowledge. This was a great video, from prep to paint the entire process was easy to follow and understand, thanks. A remarkable finished project waiting for the next step, can't wait. See you next time. 73
What a great looking PSU. Aside from the symmetrical component placement on the outside, the paint job really does bring it to life. Good job on something practical and really useful.
I remember in 1985 taking a course on electronic assembly methods while getting my AA Electronics degree. They had us bend the metal with a break, and rivet, we used the wrinkle (or crinkle) paint for the chassis and this brings back memories. How wonderful to see it again.
I have used wrinkle paint in the past and never knew you could bake it to get tighter wrinkles. Thanks for the info. I love you`re videos. Besides my brother who has been designing tube audio gear for 55 years, I think you are the only other person who takes so much time and care working on tube gear. Hats off to you sir.
First there is the wrinkle finish paint. Well worth watching. Then there is the transformer end bell screws insulation. Amazing information. To top if off is the waxed lacing cord for looming the wires. WOW!
The power supply looks superb. I have bought my first "proper" communications receiver a R1155 with the later type 35 tuning drive. Wish I could afford a T1154 to go with it! Only worked on domestic receivers previously - I have a lot to learn. Keen to see the next instalment of the BC-348-Q receiver restoration - nothing like the R1155 but looking for overall tips and tricks.

Great job, Carlson. I am impressed with your attention to detail. But, I expect nothing less from you based on viewing your past work. The coupling due to the screws not being insulated is one that most would miss and I am glad you brought it up. Every nut, bolt, washer, spacer, insulator, location of components has a purpose. Painting and finishing in restoring old gear is a subject where you and David Tipton are very skilled.
@@MrCarlsonsLab Your Ultraprobe saved me that much money in its first two troubleshooting outings. I seriously can't thank you enough for your wonderful inventions.
I really enjoyed watching this PS build. Reminds me of my youth, trying to figure this stuff out with car radios, a small junk box, and a copy of a WW2 ARRL handbook. No Elmer, sure could of used one! Even though I worked my entire life in electronics, I'm still learning new stuff from you. Thank you!
Thank you for the explanation of the transformer bell bolt insulators. I was repainting a rusty transformer in a piece 1970s hifi and three of the bolts had an insulator at both ends, one bolt had an insulator at one end and a star washer at the other - I believe its purpose was to pass chassis ground to the transformer enclosure.
I really learned a lot about the transformer shorting. You explained and demonstrated that very well. I spent some years lacing wire for AT&T and Western Electric and it was neat to see it used in this project.
Fantastic content. And for anyone who hasn't joined the Patreon, it is the best value I have ever run across. If only I got that much value out of my money at the grocery store. Ha.
I had a good chuckle when you described cable lace as heavy duty dental floss... It's a superb analogy. Beautiful job on the paint; proof that 90% of it is the prep.
Nice to see the loom being laced. I have a Bobbin of that waxed twine from my days in UK Telephone exchanges back in the 80's. By the time I left the exchanges and went into satellite communications in the 90's (with the same company) they had abandoned its use and switched to cable ties. Didn't look as nice but it was a lot quicker. The knot we were taught wasn't just a simple loop and pass through. Each knot would hold even if the twine to the next knot was cut.
We are still using waxed nylon cord or zip ties depending on the manufacturer and situation in tha US Telco world. Any cable being attached to a vertical surface is laced not zip tied as cable will slide through zip ties but rarely through a proper lacing job.
This turned out so well. I had an idea of how to build a power supply, but your explanations just make everything make more sense. I like how you had a Hammond box and a Hammond branded choke/reactor as well. Just really neat how that worked out :)
Love it! I'm fixing up an Eico 666 and went with the VHT Wrinkle paint for the case. Haven't sprayed it yet, so your tips on using it were great. Cheers!
Another spot filled with nice warm goodness.... Old stuff is just so cool... I grew up just on the cusp of tubes being the thing and transistor were the newcomer...
1:05:10 - I've heard from several UA-camrs that while those ceramic tube sockets looks nice, the contacts don't wrap around the pins; they only contact the pin in 2 places.
Nice, clean work. Use chassis punches, much cleaner hole. I used to build (5U4) tube power supplies all the time when I was in high school (1970). Not much call for them anymore. It's nice to see somebody actually build something instead of just breadboarding it. The inductor (reactor) is called a choke. The "L" in solder is supposed to be silent. Current meter is called ammeter. (amp meter). The tube sockets are called octal (8) and ceramic is used in high heat situations. All AC wire pairs should be twisted, especially the heater wires, all the way to the tubes.
Amazing work. Maybe the most surprising thing is the tiny size of the two modern filter capacitors in comparison to the rest of the vintage power supply components. Maybe you should have rolled your own foil and paper capacitors so the entire thing would have been vintage?!
Back in the day, learning how to lace cables was a critical skill for apprentices at Marconi's in Chelmsford, England ... and many other firms way back when we still took pride in our manufacturing industry.
That's a beautiful build ! The looming of the internal wiring is the mark of a true conscientious professional. Not many expend the time and effort on details few will ever see once the project is completed. Great job ! Everyone should take note of your discussion on transformer placement when designing amps and power supplies. Also, your explanation of the importance of isolating the transformer shell screws when beautifying old, used transformers is vitally important. This is a first-rate job start to finish. 🏆
We used waxed twine when working with AT&T co-locations on customer T1/DS3 crossover bays back in the 2000's. AT&T specs required all connected wires on the back of the customer's and AT&T bays have the same stich you used on the power supply cables. I still have some of those twine bales around the house and use them when wiring my own projects.
My father owned an office machine business and restored a few antique typewriters, that used black wrinkle paint. He used my mother's oven to heat them and get the wrinkle effect. They looked like new when done. Not sure my mother liked the paint smell in her oven and the house, lol.
Wonderful episode. Was enjoying settling into the longer format and then BOOM blown away by how beautiful the PSU turned out. Inspires us to aim higher with our own projects. And yes, I would like to see the facia restored on the radio to suit.
Wow that's beautiful! I appreciate the transformer advice as well. West Marine is a good source of waxed cord used for "whipping" lines (ropes) to keep them from unraveling. I LOVED the machine and paint shop! Great job improving your channel while keeping the old "Mr. Carlson's Lab" charm. Also, one of your Patreon circuits allowed me to increase the output of my Nano VNA so I could use it for a signal generator. Take care.
as far as wanting to see you repaint the radio chassis, i'm all for it. it'd be really interesting to see how you re-letter all the switches and dials.
Great advice regarding the transformer bolts. I didn't know about that but, thankfully, I had purchased new card washers to replace the old ones on some transformers that I restored a while ago. The end result of your build was excellent as ever!
Yet another quality video & a quality build... just sit back with your favourite bew & take it all in. What a brilliant way to learn! Thank you Mr. Carlson:)
As I’m watching this, you mentioned “that’s a catch for new amplifier builders, and even some experienced ones as well” when you were talking about transformer orientation… The Soldano SLO-100 had the transformers mounted in their same orientation for over thirty years in production… and FINALLY their design was changed when the company sold out to “Boutique Amplifier Distribution” I guess nobody had the guts to tell Mike Soldano he might have made a small mistake! 😂
Paul you are a real profesional, that power supply build looks like it came from a factory. Looks very nice! One note on making larger holes for transformer's wires and tube sockets, etc., I use step drills and/or chassis punches.

Beautiful work Mr. Carlson! Love the wax lacing twine especially. I get mine from McMaster Carr - part number 3858T13. I'm really looking forward to seeing the BC-348 restoration. Thank you for all the hard work thus far!!
They sure don't make 'em like _THAT_ anymore. I didn't know that wrinkle coat paint could come in a spray can! Get the paint prep right, and it doesn't get much easier. Thanks Mr. C! 👍
Paul thank you so much for the transformer tip, i would have never thought that the screws could create an extra turn and load up a power transfomer, it makes perfect sense kinda like a shade poll motor, and i wounder if that could also induce hum into the chassis. I just recapped a conar 230 all of the ceramic caps were incredibly microphonic, and a replacment very cheap filter cap had started failing. And began to bulge very very slightly kinda hard to tell unless you fell the top vent and the bottom seal. That issue is now fixed, but it has a lot of hum, even the manual says it would, but looking at how the filaments are wired and were the power transfomer is located next to the output tube. I know i won't be able to get rid of all the hum, but i do belive re doing the filament wiring would clean it up a bit! And now seeing you tip on the power transfomer ive gotta do some testing now. thanks very much For your time Friend good day to you guys!
Beautiful build. Back when I was a kid, you could get wrinkle in colors, no more, but you can overspray the black with colors w/out loosing much wrinkle. I NEVER new about the transformer screws. Good point.

Mr Carlson's junk box has more treasures than most barn finds.
Even every screw head is perfectly aligned. Perfection!
That means either they are too tight or too loose. From an OCD electrician friend who described that properly tight has only one unique direction.
@@Drew_Snydermann they can all be tight and lined up when you have access to both sides like that. It's just tedious to set them all up that way.
@@Drew_Snydermann You have a screw loose
@@Drew_Snydermann I'll go along with you. In fact, blade type screws are entirely horrible, and Phillips are the only way to go. And don't bother lining them up!

Beautiful build. Back when I was a kid, you could get wrinkle in colors, no more, but you can overspray the black with colors w/out loosing much wrinkle. I NEVER new about the transformer screws. Good point.
VHT has wrinkle in black, grey, red and blue.
