Hey all, first time poster here. I recently picked up an R84 that was a real basket case, although it was mostly there. It was full of bird poop and mouse nests, apparently it was in a barn or something for some time. When I first got it home, about all I could get out of it was the "pop" of the speakers when powering it up. No lights, no sound, no activity of any kind. Well, a lot of dinking around later, it's almost there. It seeks out records and plays selections properly. I adapted an Audio Technica AT-3600 to fit the tonearm, as the Shure was missing the stylus. Some JB Weld put the pieces of what was the grabber arm assembly back together. A couple of Xmas tree lights replaced the bulbs on the preamp board and fuses were replaced in the power supply. Some new fluorescent starters got most of the lights back, and cleaning all the connections brought the CCC and everything else back to life.
But...No sound.
Strangely, before I replaced the bulbs on the preamp, for one time and one time only, it came on and played a record at full volume. Then I powered it off to check connections for the vol control, and when I brought it back up, nothing. One of the bulbs on the preamp was bad, thought that would do it, but to no avail. I'm thinking perhaps the relay for the mute, I'm also thinking perhaps just running some RCA's off of the turntable and handling amplification externally.
Ideas?
