Interesting find Harry. The prices are a clue to the quality though, you can imagine the quality of the audio output transformers. I would probably junk the tubes/valves too and replace them from a known source. Resistors in noise-critical positions would need looking at.

But, it is good to see them being available, so there still exists a market for them.
