For sale is a single mono Webster TP-90B tube power amplifier for $250 or reasonable offer. These are described as having "High sensitivity, wide dynamic range, low distortion, and smooth frequency response." These are the same amplifier as the Allen Organ 90, just in a slightly different chassis. In the electronic organ, I believe these amplifiers were used to reproduce the full range of frequencies down to about 32 Hz.
This one works and is in nice condition for its age. It does pass some 60-cycle hum which a new owner will certainly want to address. Paint and cage are in reasonably good condition, the best I've seen for one of these, though not in perfect shape by any means. The previous owner left the original electrolytic capacitors in place but replaced them in the circuit with new electrolytics under the deck. The coupling capacitors between the 6SN7's were also replaced. With some work this will be a great amplifier.
Tubes are not included.
Please check out the photos and let me know if you have any questions. Local pickup just north of Seattle is good. I can ship inside the United States, and maybe to other countries as well, though this amplifier is heavy. I will wait to pack until I know where it is going. Offers are welcome.

It looks like the photos didn't make it. I'll try and figure out what to do about it. If you are interested, PM me and I'll send photos directly. Thank you.
