Restoring a Vintage RCA Stereo Cabinet?My grandfather recently passed and I'm looking to restore his RCA stereo cabinet. The left speaker is blown so I'm replacing the speakers. But the 8 track doesn't work (it sounds like its trying to play but it's struggling to wind and it makes loud noises/vibrates when you change tracks) and the record size switch is stuck. Would anyone be able to tell me if the 8 track is salvageable or if there's replacements out there? if there's any manuals/schematics available? Or the best way to go about fixing the other issues? The model number is VTT300W serial number 424310322.
