HI,
I'm amazed about amount of knowledge you guys share on this forum.
I was only a reader but finely I've sign in.
Fortunately my collection of 70-80's audio grow up again-Marantz SD 8000
In a mint condition. I've replaced optocouplers and now new problem show up, main motor runs about 3 X too fast just the same problem you have couple of years ago.
If you were so kind and let me know (if you remember of course) what was the fix for the speeding motor. I’ll greatly appreciate your help. I’m waiting for the service manual but to tell you a truth I’m little intimidated by complexity of that deck.
Million thanks in advance for any help you can provide.
