I have this Akai on it's way from a man who has had this RTR since new in 1982 I love the look of this unit I like the fact it looks like a twin cassette deck they stopped making this modal in 1985 it was the last RTR that Akai ever made as cassette tape took over until it was replaced by minidisc in the 90's I still say Minidisc was the best home recording format that ever came out now back to RTR a lot of studios are closing & the RTR are being sold on to the public & like cassette it's making a come back I love the fact that it's a hands on formats unlike the cold download where you get no words covers but most of all somthing to hold in your hand I feel they will never truly get rid of RTR Cassette Minidisc

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

Hello,

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.

Regards,
Kevin
