Hello all,
I bought an old amp from a junk store the other day. It is an American Telephone and Telegraph (AT&T) guitar amp. Model # 803, serial #1687.

It has a volume control and tone control(which is also the on/off switch).

It has Sylvania tubes and a 10" speaker. I sounds great. Very ratty. The speaker is in good shape and with my Epi Casino, I can almost get Link Wray type noise out of it when everything is cranked.

I've search the web and have found nothing about these amps. I thought it might be a home made kit bit the schematic is pasted on one of the sides.

Does anyone know anything about these?

Sorry, without pics - it doesn't exist!

when am I going to learn?

Wha?

Never heard of an amp made by the Telephone company. Anythings possible.

Interesting!
The only thing I can remember is this quote about the tube circuits, not the amp itself:

From "The Fender Amp Book" by John Morrish

"Amplified sound had been around almost since the invention of the thermionic valve or vacuum tube by John Fleming in 1904. The triode, the first amplifying tube, was patented by the American electrical engineer Lee de Forrest in 1907 for use in the detection circuits of radio receivers, converting radio waves into barely audible sound to be picked up on headphones.(...)The patents on all early tube circuitry were held by the American Telephone & Telegraph company and Western Electric, but these companies permitted the tube manufacturer RCA to reproduce the designs in the handbooks freely issued to anyone buying the tubes."

Regardless of " worth" sounds like you have jewel. How much did you pay?

Very cool RobberBride. Thanks!

I paid 25 USD. The thing I find interesting is that there are no identifing marks on the cabinet except for the model/serial numbers which are embossed on a metal tage on the bottom of the amp. the AT&T schematic is glued to the inside of one of the sides.

I'll take pics tonight. It sounds really cool.
