Amplifier produces a "crackling" noise through speakers when volume or
l/r balance is adjusted, then settles back to normal sound/function
when adjustment is made and the controls are left alone. It does it at
all volumes and strangely how bad the crackling noise is, depends on
how "heavy" you grab/touch the volume knob?? (perhaps pure coincidence
but i thought i'd mention it).
Does anyone know if this is a serious problem or one which can be
fixed without much hassle/expense, or should i get rid and replace.
(its only started in the last week or so.)
