    NOTES: 1.) I said "electrolytic" with regard to speaker.....meant to say "electrodynamic" :) 2.) The elaborate wood framing for the rear of the Model A cab is the limiting factor, not the vinyl material. This was a hot rod when I got it, and detailed, expensive restoration is simply not practical. 3.) I believe that reducing the impedance of the Microphone channel (i.e. from 5 Meg down to 500K will solve the problem with excessive volume......however, for use with acoustic guitars (with ultra-low-output pickups) it may work just fine as-is. It's up to the customer.
    UPDATE: When I delivered the amp to the owner, he tested it with a couple acoustic guitars that had add-on low-output pickups......and the tone was incredible !!!! Much, much better than in my audio demo, especially when plugged into the previously-unusable Microphone input (at a setting of 3). It's obvious that this amp had a specific purpose, and solid-body electric guitars wasn't part of it.

      Doug, Posting this here as well:
      I found a schematic for this amp that uses the proper tube complement that you appear to have there.

      It's also an unusual schematic as well. Check it out.

      So this amp Doug does everything a harp player wants - but for a tubby, low ohm speaker set of the Bassman or Concert amp variety. The other name heard is Dano Commando, or Masco, in harp land, but something like this or the National would invite harp players to try mic element, speaker box, & driver experiment. (Echo labelling evokes the Hohner harp model.) I am down to four tube heads GA 40, M-8 (Cal Tech's favourite) AP 14 and Arkay 12 but am up to 40 box.driver,impedance combo possibilties

      Uncle dog - I’m curious - I occasionally come across vintage amps at estate sales, and have no idea what this era of amp would be worth in decent condition , what would I expect to be a “fair” price for a working OR non-working amp of this era? I’ve never seen one this pristine, but you never know... this one truly boggles the mind in this condition...unbelievable!... man, oh man.
      Uncle Doug, you do amazing work, enjoyable and great learning in the process!

    Uncle Doug, I have followed you for several years. I just wanted to say, you are one of a kind. It isnt often one finds a master craftsman who is both willing to share his knowledge, and at the same time make the lessons entertaining and enjoyable. Thank you so much... I delivered furniture in my teenage years, and my delivery partner José used to tell me (after a customer had thanked us for a job well done) "my friend, we cannot survive on 'thank you' "... his point being that if the customer were really that thankful, perhaps they could've offered us a monetary token of their appreciation... all that to say, I will be sending such a token shortly, and encourage others to do the same. Thanks again. -JB

    Your tour of this museum grade amp was spectacular! It was great to see you preserve the original electrolytic capacitors boxes to keep the original design look, vibe and smell. I noticed that they had markings that said information of the patent was included inside the box. You should have left a note inside these time capsules identifying that the repair was performed by the legendary Uncle Doug! And your sense of humor in this episode was in rare form this time. Ear wax! In the last flyover view of the inside of the chassis, I noted the mains white neutral wire was still soldered to the fuse... Built in invisible death capacitor? Lol !! Many thank for this.

    That old Gibson amp is in amazing condition for its age and should probably remain so if it’s kept in that excellent padded soft case. It really sounds very bright for an early guitar amp but I guess it needed to be in order to cut though the orchestra, they could be quite loud. I admire the quality of the work you’re putting into the hot rod. An old friend of mine, (now sadly passed away), was a car mechanic whose hobby was restoring old cars, (he really lived the dream). Watching him working on an old neglected car and turning it into a thing of beauty really impressed upon me how much thought and hard work goes into car restoration.

Good to see and hear you again and glad you're taking some "me time".

      Things like that and the parallel terminal strips, instead of the haphazard linear "dead bug" type construction, shows that Gibson was putting quality and thought ahead of mass production. Also forming the wire connections with 90° bends and fitted to length do the same. Then canning every tube except the rectifier probably wouldn't make it past a cost benefit analisys, bit they went the extra mile for a (probably?) tiny improvement in audio quality. You can bet that the fixit techs in repair shops spread the word quickly to musician customers that Gibson built works of art on the chassis. This had to speed up repair and also made the factory QA process faster and more accurate, making for better reliability and cheaper repair costs. The neater layout probably sped up manufacturing as well, since assembly line techniques would easily fit in, instead of one person having to solder every single connection to build an amp. The terminal boards were probably manufactured and tested independently before any connections to the board happened.

      Those tubes predated glass in the mid-30's. Mine says 5U4 (no G) on the chassis for the rectifier which I think was had the steel tubing. Most of my metal tubes had 1941 RCA date codes (the ones I could find a decoder for).

    You know just when I think that you have demonstrated all of your many, many talents you throw me a curveball. First off, what a joy it must have been to work on such a pristine example of a prewar amp. And the bonus of an amp that apparently had never met a rodent of any species. Masterful job of stealth upgrading of the electronics. I have watched videos of different people melting wax out of ” waxeys” and replacing the ”guts” with modern replacements, then repouring the wax using toilet flange ring wax to match the color of the original, to hide the modern component but I had not seen anyone tackle a box cap before. I have one that I need to do on a 1929 RCA Radiola, I just hope it is wax and not tar, the cardboard is charcoal gray color. The finished product was absolutely beautiful. The only thing that I think you could have done to make it more period-perfect would have been taken three pieces of modern cloth-covered multi-strand wire and braided it into a power cord, much like the wiring on the output transformer. Would have been a lot of extra work though. That amp sounded amazing for it's age. I can see why it would have been a favorite of guitarist in a big band setting, having to compete against dozens of horns, woodwinds, and percussion to make their instrument audible. That microphone input had an unbelievable amount of gain, wow. I guess the microphones of the day were not the most sensitive, so maybe it required a lot of gain, but fighting the feedback must have been a real challenge. On to the Special Coupe. Your solution for a substitute for a really big English Wheel for bending that curved top was ingenious. I bet it took an awful lot of very careful brute force to get that compound curve to match the roof line of the top. Beautiful craftsmanship and amazing fabrication skills using improvised tools. I really liked the use of screw heads to bridge the gaps for welding the top to the body. Another stoke of genius on your part. I wonder if when that car was built if all of the nails we're just driven straight through the sheet metal or a small hole punched first an the the nail driven in. The holes appeared to be 6 or 8 penny nails, into oak. Would have taken a very practiced hand with a hammer. Knowing Henry Fords reputation he probably would have insisted that the nails be driven without pre punching for efficiency’s sake. I will bet that you are correct about the body being a roadster with a metal top added. Didn't the Victoria have all of that extra roof trim? I bet you are happy that 3M developed a fiberglass reinforced body filler. I can just imagine those channels filled with ”Bondo” first good bump and Bondo would be hitting the pavement. Great body work, and I know how much work that involves, I did about a year and a half working for an auto rebuilder. Buy two wrecked cars and make one good one out of them. Lots of body work, endless hours of wet sanding and painting. Working there and another job while going to electronics trade school. Uncle Doug, you seem to be a ”Jack of all Trades and Master of All”. I stand in awe your abilities.

    • @UncleDoug
      @UncleDoug  5 років тому

      Thanks so much, Mark. I am flattered and appreciative of your kind words. I agree that concealment of the power cord wires would have been a nice final touch. I will do this if I ever have the opportunity to re-open this amp. I have no idea how the nails were driven through the rather thick steel. It was probably too early for nail guns, and I cannot imagine doing this with a tack and hammer. The metal bending really did take brute strength. My wife was highly amused.....watching me sweat and curse in the back yard, while she sipped her coffee in the air conditioned kitchen. The neighbors, however, wee probably not as amused :)

    That was a BRAVE move with the oven Doug, last time I used my wife's oven, is back in the early 90s when I thought I could bake clay and thought it was extremely humorous to make a well, for lack of better words a phallic symbol.. The oven did not get to the 1500 + degrees as needed to bake clay, but instead made a stink of the house and set off the smoke detector. Granted back then, I was "experimenting" with certain substances, but I never touched her oven again.

    Ah, Uncle Doug... The Uncle I wish I have but never had.
    All the tube / valve stuff is still Chinese to me. But I must say it is a pleasure to watch a professional doing his thing.
    I mean, I guess many people out there could get this amp up and running putting caps just as you have shown earlier.
    But the attention to details puts all this apart. Like putting, and taking the time to do so, caps inside those boxes to make the amp look more “virgin” and to hide other caps behind the PCB.
    That is a pleasure to watch.
    Now I see Mr. Carlson has uploaded a video too. This is a good week.

    Hi Doug - thank you for these wonderful videos. I'm restoring an almost-original late 30s EH-150 chassis right now and your video and descriptions are very helpful, indeed. As is the very detailed interior footage. The components and layout of mine are nearly identical to this one. Just wanted to (respectfully) mention a couple of corrections to your cap replacement designations - the fourth underside cap is a 10uF 25v cathode bypass cap from pin 10 to 10 (running directly underneath the 3K cathode resistor from V1, and apparent just counting backwards from 13), not 9 to 9 as you indicate, easy to get confused with so many terminal points - and the fifth and final underside cap is a coupling cap from pin 11 to 12 , not 10 to 12 as you mention. One other hint for those who may be restoring this style of Gibson amp is that the speaker plug pins 3 & 4 need to be shorted to complete the 5V filament circuit. Again, many thanks for your excellent instructions and explanation. (:

    Amazing amp....never seen one like this. Interesting the different choices the manufacturer made to address phase inversion and tone control.

I have a pair of nice moustache handle's off of early Ampro type cabinets. I know their slightly different then the Gibson type, but I'm not aware of anyone reproducing the original. It looks like it would have been easier to make the 28 Ford a convertible than to repair that mess.. But you made it work.. Great stuff. I like the auto additions in the videos. Be well, Tom
