Looks very "Silvertoneish" , probably made by them or some competitor. Should be very easy to trace; just do it and post the schematic, plus some "guts" pictures. I love bargain bin specials.

Well, it's not a Silvertone, it's not made of pressed cardboard, he he. Better for you.
Please re-take the schematic picture outside on a sunny day, to make it more readable.
Steady your hands with a chair or something and press the button slowly.
Beautiful amp, excellent bargain.

Hi Stewart, thanks.
Well, readable enough.
Interesting little amp, and rises a few questions.
By the construction technique , it's very '60s, the golden age of department store tube amplifiers, in fact that panel and graphics are very "modern", *but* the style of drawing tubes, and the fact of using them "starved" (huge plate resistors, little or no bias resulting in low plate voltages), the general "economy of components", comes straight from the '40s, or even earlier, when components were scarce and expensive and you had to pull up to the last dB of gain from a tube.
I guess it was designed and built by some "old hand" , I mean somebody who was already old way back then, and with a lot of experience.
I think you have a jewel in your hands, it must sound good.
The speaker looks quite good too; if you could just provide some picture .... [:)]
Just for fun, play some White Stripes material through it, or some smokey Chicago Blues.

Very probably 63. Any earlier amp would have used 6V6's for the same power output.

It's an old OEM manufacturer, and surprisingly still in business, considering the outsourcing-sickness that affects and is killing the US.
