OK, here is the amplifier, front and rear, with the leather upholstery.

I am very pleased with the way this turned out, and with 10 W it’s just loud enough without the booster amp and extra loud with it.
I took it to the old music store in downtown Fresno and we played it yesterday with the baby blue Stratocaster and I blew the mouth harps. It was enormous fun.
I still haven’t figured out the best way to put a handle on it so it can be transported, but really this is not supposed to be transported. It’s a home unit.
So I told my wife I was going to go back to work on the car today and she told me it was going to rain and it looks very gloomy.
The last time it was like this, I decided to stay inside and build a new amplifier. A whole week went by somehow and I never did touch the car.
Anyhow I have two sets of tubes to work with currently. One from the Zenith radio and one from the Silvertone radio.
What I don’t have is a proper rectifier tube and because of that I may decide to do it all with a solid-state rectifier.
This means I will probably have a low voltage power transformer and a high voltage power transformer, rather than a special transformer combining the two.
I might just use the 6x4 dual diode tube rectifier from the Silvertone radio. It will certainly provide enough power, but these are known to be the tubes that die first and most frequently. The rectifier.
I have collected 14 different vacuum tubes and they all appear to be in good condition, however some of them are high frequency radio amplifiers not suitable for audio amplification.
They may however be useful for strange distortion effects. They may have strange microphonic properties. I haven’t looked into any of that yet.
But aside from playing the guitar every day now, I also have been studying antique tube driven electronic amplifiers. I don’t have quite everything I want yet for a successful build but I was planning to work on the car before attempting it.
