Vintage Tube Amp

Up for sale is one H. I powered it up with a Variac Transformer. This could be a great project for someone who wants to tinker. Manufactured in the late 1950s (around 1958). It includes a multiplex output jack anticipating future external stereo decoders before the FCC officially approved the FM stereo standard in 1961. Utilizes a direct-drive tuning setup through a planetary gearset (vernier tuning) rather than a traditional springy dial-string. Built using Scott’s wide “C” case/chassis format.

I tested the unit the inputs work I cannot get the radio to work. I’m not sure if I need an antenna or what.

This mono amplifiers in pretty good condition for its age. I’ve only performed a light cleaning. It is untested and in the exact condition that I received it in. I have not powered it up. I’ve not tested any of the Tubes. I’m sure it will need a check up by a technician and some components replaced. Take a look at pictures for the condition details.

Please reference photos and condition notes above. The guts on this model are the same as the Pioneer SX34. This Knight model was re-branded for sale. This particular unit has (2) Matushita 12AX7 Tubes and 4 ECL82 Tubes. Unit is powered, tested, and working. Scanned the FM band and adjusted volume during test. Overall good functional condition. Powers on and works. Audio output and FM band were tested. Overall good to fair cosmetic condition.

It has NOT been tested, and will require restoration before use. The output transformer is missing. You will receive the amplifier shown.

Works and sounds good.

Comes with two of everything. Everything powers on and the tubes light up. That’s all the testing that was done.

Missing 4 output tubes (6BM8). Has slight surface rust all over. Knob on left is not original. Weighs about 29 lbs before packing. Terminals in rear have separation – see pics. The screws that hold cover on were missing so I put 4 in, but not original. There may be some things I missed. See pictures as they are part of the description.
