Two years on...
Same radio. And it's been mostly sitting on a shelf collecting dust. I just missed out on an opportunity to sell it, because it now has an odd problem.
Every time I turn it on, instead of the sound gradually coming up as it should, it remains silent until it suddenly "pops" into playing mode.
No, there is no "pop" - what I mean is, that it suddenly comes on instead of gradually coming up.
I think the sensitivity on the upper end of the AM band may be a bit lacking. I did go over the set's alignment today and it helped on the highest SW band, but there was no real improvement in the other bands.
I've switched every tube in case the sudden volume was a tube cathode - no dice, it still does it.
I suppose it is time to get out the signal tracer and see if I can find where the sound stops at turn on before the tubes are fully warmed up.
Any thoughts, guys?
