[Hallicrafters] S38C - FADING

[larryasp]

Something like this came up at  our radio club meeting yesterday - start
looking at plate resisitors after warm up - one could be heating up and
going off spec. Change out old paper type capacitors.

Hi

My recently "restored" Hallicrafters S38C worked weel for many months,
however, it now starts up OK but then fades to silence - see the following.

The AF side of the set seems fine and does not "participate" in the fading.

On start-up, the panel light glows bright, then dims, then comes up to a
useful brightness, the set plays, then fades. The band-switch has been
cleaned, ditto the others.

A while back I replaced the main power capicitors, so I do not think that
they have much to do with the problem.

Any help (on or off the reflector) would be appreciated.
