I recently noticed a slight hum when my preamp is on the phono source. I only notice it when music is not playing. The higher the volume the louder it gets. It still occurs when the TT is completely disconnected and It only occurs on the TT source. I removed all sources and it still occurs. The preamp is a B&K MC-101. It has an internal MM/MC switch. I have the switch set to MC. The TT is a Technics SL-Q3 with a Denon DL-103.
Any thoughts?
