Akai GX-9 Tape - unkown issue
HTML-код
- Опубликовано: 16 сен 2024
- Almost always when the device is just started up, the playback is not working, the tape is moving but without any audio and therefore with a loud mechanical noise, then the tape reacted to no switches at all, and I have to turn it off completely. When the device has the operating temperature it's mostly working okay.
Maybe anyone has an idea:-)
Change the cam motor belt and everything will work fine
That sounds like some ground screws have worked loose. I have a Sony TC-FX705 that had a similar issue come to find out the logic control circuit board was grounded to the case and the screw that made the ground had worked loose tighten it up and no issues at all. It also could cracked solder joints I would also check for circuit glue that stuff becomes a electrically conductive was it starts turning dark brown, gently scrape it off if any is found. It may be dirty tape sensor switches too. 2 years old so you may already fixed it by now. Very handy as general trouble shooting check the obvious right?
Many thx for your suggestions, maybe I can check this out in the next time 😃 It is very hard to find people who have experiences with these old tapes.
@@Oettinger53 Your welcome hopefully that will arm you for a better plan of attack sort of speak 😃😄👍👌

You must replace micro switches underneath of rewind , forward and fast-forward
Hope this will solve problem.
Cheers
Thank you very much. Do you maybe have some specs of those switches?
The voltages on the motor board are not set right. Check the service manual and adjust VR1 and VR2 as instructed there.
Thank for the information, but I did this 2 times in the past and it did not really help:-( Also the voltage is very dependent from the operating temperature, don't know if this is normal.
