I turned each unit on for a very short time. I unplugged these units whenever possible and cut wires only when there was no other option. One is from a model 1966 monograph turntable unit and the other 2923 reel to tape.
Sold completely as-is. These little tube amps are 10 watts each and were pulled from a pair of Webcor consoles. These were both sold under the custom 10 name by Webcor and meant to be a matched set, so audio qualities of each are identical.
Tubes lit up on each and I did hear static out of each, but not leave them long enough to test further. Thanks and enjoy. All tubes pictured are included but untested. These units are untested.
They look identical, but there may be slight differences between them.
