re: GX-77

Hi , I have this beauty too. When 5-10 minutes left on reel, reel motor gets "tired" and the machine stops. Any ideas?

re: GX-77

I'm sure you have this fixed by now. I had a similar issue. I replaced all 3 belts (2 reel belts and the main capstan belt). That fixed all the issues.

re: GX-77


When the reel gets "tired", does the servo capstan motor (tape speed regulator) continue to feed tape to a non-rotating take-up reel? Or, does the take-up reel sustain tension on the tape with the capstan motor stopping tape feed?

This condition is a known issue with this model deck. There are some good repair videos on YouTube addressing this condition.
