Vidor CN429 'Lady Margaret' fell silent
Hello everyone after a long absence from these pages. I have a sentimental attachment to a Vidor CN429, which was beautifully restored some years ago. Unused valves, all old capacitors replaced, both 90v and 1.5v batteries at full strength, worked like wonder for years. I listened to it maybe once a month. The other day, I opened the lid, and there is absolute dead silence. Not a squeak, not a hushed crackle. Only the week before it was absolutely OK. Now it is as silent as if I had not switched it on.
It had not received any physical shock. Circuit voltage measurements still give valid readings. I checked all soldered connections, they hold fast. Both batteries are at full power. Whatever I turn, touch, knock gently or refit, there is no sound output whatsoever. Could anyone please suggest any possible path to a solution? Hoping against hope, Miklos
