Hi, I just finished restoring my Akai GXC750D cassette deck, and I decided to share some pictures with you guys.
That Deck I bought on e-bay for 50 US$, and it had some issue with rew and ff motors. What I did during that restoration:
- first I changed all belts, here I need to tell you something, small belt which running counter is very important as main big belt, why, because counter has one part which generate signals during tape is running, by this deck “knows” that all is OK, in moment when that part of counter stops generate signals, deck immediately goes into stop mode.
- As you can see on pictures I disassembled all that I can clean and lubricate critical parts on deck mechanism.
- I have changed ALL capacitors (as you can see with lot of Nichicon MUSE and Elna capacitors)
- I have changed four transistors
- I have changed critical resistors with metal-film resistors (to reduce noise)
- I restored two pinch-rollers at http://www.terrysrubberrollers.com/
- Adjusted by original Service Manual (and by three original test-tapes)
And now it will be great partner to my Sansui G8000 when Sansui will be finished!
Regards!
