Default Dyanco problem

found that sound is actually comming out of both sides. when i fire
the amp up it stats up as normal and the music starts to come up for
roughly 2 seconds (as the tubes warm) it than reaches a peak and
instantly dies. the whole process lasts about 2 seconds.



If sound is common to both sides, the culprit should be common to both
sides. If the driver uses a single tube for both channels, maybe the
filament supply should be checked more closely, both for that tube and
all others. Wrap thin wire around individual tube pins to check what
is actually present. This is good for all voltage checks.
Especially check for wires which may be partially grounding or
otherwise touching.

Nothing like a difficult problem to liven up the day.

good luck
