I have a factory assembled Dyna PAS. When I acquired it, there was a steady state buzz in both channels. Thought it might be in the power supply, so replaced the whole power supply with the Gearhart board, which replaces the quad cap and selenium rectifiers and filters. The buzz is the same and has not been changed at all. Interestingly, the preamp sounds much better.
So the preamp is completely stock other than the power supply board. The buzz is not super loud but is steady state and present on both line and phono. Any suggestions on the next place to look would be appreciated. Thanks in advance for your time.
