Need some help here please.
I have a Krell KSP 7B pre / KSA100S power amp which has recently been giving me problems
When I turn the combo on, most times it is fine, everything quiet. After a while though a high pitched 'white noise' type sound is heard - even with the volume muted.
In addition, sometimes there is a hum, apparent on all sources, but worst with the phono stage. It will be virtually silent, then this too suffers with hum.
When I use another pre amp, no problem.
Any help would be really appreciated.
