Vintage Marantz PM-630 issues
I've recently dug out my old Marantz from my storage room and it's been working fine for a week or so, but now it's not working.
When I turn the power on, the speaker systems lights turn on fine, but the other lights like the volume display flicker for a moment before dying. Sometimes it would function fine with the lights normal for about 2 minutes or so, but then the lights flicker and die along with the sound. The sound sometimes works for a few minutes even after the lights have died.
I've checked the fuse and it seems fine (as expected) and the voltage settings are set correctly as well. The relay switch also works fine, clicking 1~2 secs after turning the power on.
Any help suggestions would be appreciated.Thanks
