Maratnz 2275 Stereo Receiver Repair Part 3 - Did I Finally Figure it Out?

Puzzling source of the intermittent issue with the 2275 finally revealed itself.

The dreaded intermittent problem; great job getting that fault tracked down and remedied. Those are sweet sounding receivers, should make the new owner very happy.

Yeah - the on again/off again issues can drive you crazy.

[@amosperrine1909]

Just recapped, etc. mine. Sounds great. Recently hooked it up to a pair of Totems via a Dynaco ST 70, next up is the ST 35.

My Marantz 'grail' receiver is a Model 19...I'd love to have one cross my path someday.

That transistor with the screw is the regulator for the radio section. Would not affect Phono or Aux.

Receiver went to a new home on 12/20. I know the owners - no issues since. Maybe a cold solder joint that tightening the screw addressed?
