...and lastly, the radio has not been used since the last time I

it about 10 years ago. Then it worked fine, no I tested it again and
suddenly there is this problem. It is entirely possible that it was
knocked (I hope not dropped) while in storage, but there is nothing
visibly broken, and all the valves do glow.
BTW, I tried removing the valves one by one and seeing if one valve
did not "make a difference", but this approach did not work, any valve
removed results in no sound at all.
