Doc B. said:I was working under assumption that you were sure the noise was coming from the preamp. If you haven't already, you will want to isolate which piece of gear the noise is coming from before changing out any parts.
You were right Doc, the pops and the sizzling sound are from the quickie without any dubts (tested with headphones and no amplifier connected), I was thinking if also the power amp could exacerbate the problem with those big electrolytic output caps...
Thank you
