Hello everyone. I just acquired a GF-8989 off Ebay. I am 56 years old and I had one of these when I was 16. I loved it. This unit had quite a few issues - but I am slowly getting there. The list of non-operation was quite long - LW/MW didn't work, tone controls didn't work, record from internal mics didn't work. I'm getting there, but there is still some issue with record from DIN. Unit is fine as a monitor when recording and shows healthy VU levels. Playback shows the recording just isn't getting enough level on the tape. Having a blast working on this. Have a second unit coming tomorrow. Big thanks to Lasonic TRC-920 - I thought your idea of spraying the speaker grilles black looked awesome - so I have done the same.
