VC, could you elaborate on what you mean by "parts check ok"? If you haven't recapped, you should do so. In one case, a radio of mine went from being utterly dead--right down to inexplicably unlit filaments--to working great just by doing a recap. A cold solder joint or similar circumstance of bad connection may have been the cause of those unlit filaments (I'll never know fo sho) and seems a very likely culprit in the symptoms you describe. If a recap has already been done, I'd lean even more in the direction of a cold solder joint.

So if you haven't recapped--do it and see what happens...and if you have recapped, I think you'll just have to grab your signal tracer and start tracin'
