Marantz 2325 Buzzzzzz


This morning I was listening to the radio on my 2325 and out of the blue a loud buzzing sound started within the receiver. Didn't seem to matter what input was chosen. I then shut it off for 5 minutes, turned it on to see if the buzz was still there and it was gone. Any ideas on what this might be?

The site is I rebuild Marantz.com very cool site but I gather on the expensive side perhaps, well this is a "high end" group of enthusiasts.
If you haven't had the unit recapped, this is likely a warning shot. The electrolytic capacitors in any electronics that are this old have reached the end of their useful life. Time to put some money / time into it or give/ sell it to someone who can/will.

He is the dean of these vintage receivers!
He completely rebuilt mine to perfection, he will no doubt have the answer!

Good luck,
