[Boatanchors] Sentnel Radio Co. Musicair Console, Help Needed

[Carl]

If it has paper caps they are all bad even in plastic tubes.  Fix the radio 
before you fry a power or audio transformer.

I am in the process of restoring a Musicair Console Radio. Replaed several 
defective capacitors.
The radio plays now, but after warming up for 2-3 minutes, it fades out, no 
audio.

Turn it off, let it rest a few minutes and turn it on. It plays and then 
does the same thing again.

Anyone have some advice on what to check? Can a coupling capacitor do this? 
AGC tube?
Or, is it a tube? All the tubes check out fine on a tube tester. Something 
warms up and changes.
Any help will be appreciated. Thanks, Ron 100% DisAmerVet
