Hello everyone!
I was looking for some advice regarding my father's R-81 jukebox. He picked it up years back from a friend and never had a chance to fix it. He would love to have it working, and i would like to restore it for him. I have bought the service manual for it, and it seems very informative. Here is the current condition it's in:
- Powers up fine
- All troubleshooting leds are lit on power supply
- -17V lights up on memory unit
-Magazine rotates and stops at 27 or 77
-"Record playing" lamp doesn't light or display mag position
-Both make selection lamps lare off (test mode lights them)
-Digits display sometimes when pressed (slightly wiggling wires to selector logic make this go in and out)
-After pressing 3rd digit for selection, "Clock" on memory very briefly lights then goes out.
-"Data" light on memory unit always stays on solid
-And....nothing happens then. No movements. Unless you click reset on memory unit an couple times, then it may randomly select a record and play till its done.
-Unplugging P502 on selector logic makes "clock" faintly light also, along with solid "data" on memory unit.
Thinking about pulling the selector logic and checking for dry joints on connector pins. Am I ok to reflow those as long as I don't touch the ICs? Read they were ESD sensitive I think. My solder station is ESD safe, but i dont eant to mess with anything i dont need to haha. Are shorted wire harnesses common on these? Any other advice or info anyone could share would be amazingly appreciated.
Thanks,
Trenton
