Anyone ever had a 6Q7 cause the audio to fade out over about 4 sec then fade back in over about 4 sec? Darn thing did it intermittently quite a few times before dying all together.
Had this for a few decades but never looked into it because it played fine. Never knew there was the shadow meter due to the dead bulb. Re-capped, some resistors changed, new tuner bank rubber mounts. Thanks to Tom Oppat a new volume control. Never played like this before!
