The only problem I have with my OPPO 83 is it doesn't like not having a disc in the drive. It gets lonely.
So the next time you try to open the drive, it won't... Until you tap on the top left side of it.
Don't let your OPPO 83 go to bed lonely. Leave a disk in the drive.
Upgraded the Mark IIIs.
Svetlanas suck.
U.S.A. Made vintage Tung Sol Gray plate no holes is where it's at.
Also replaced the gz34s with Mullard-Hammond GZ37s. Those are the tall ones, the bridge rectifiers.
