GF-9494 tape hum fix & more

When Freddie came up to visit, my GF-9494X tape deck decided to die. We were both jinxed that day so I really couldn't beat his ass for it. Laugh Out Loud There was a dreadful motorboat hum and squeal. I rarely played cassettes with it, so didn't know the problem existed until Freddie "discovered" it. It wasn't a problem when I first got the GF-9494.

On the advice of Vladi, I got liquored up and went to town spraying contact cleaner everywhere inside the box. Big Grin Unfortunately, it didn't work - the cleaner that is. Laugh Out Loud I then tried the old "play/record switch" trick and must have worked that for about 15 or 20 minutes. Eventually the hum was completely gone!! Cool

But, the bad news was, the capstan tire had turned to goo somewhere along the way also. I still had some silicon tubing left from my last capstan tire repair and cut off a little piece (the original capstan tire is on the right).



While I was in there I sprayed a double shot of cleaner into the record switch underneath the cassette mechanism. The next thing I had to do was clean the black goo from hell off another rubber tire and the play wheel. GooGone and about 9 double-ended Q-tips later, the wheel is finally clean.



Testing revealed everything was okay so I put everything back together and popped in a reel tape of mine just to make sure I didn't forget to hook something back up. Booyahh! I'm back in business!! Cool

I'm glad you got it going! I apparently haven't drank enough for my RX-C60 to be revived! Big Grin

Vladi's a bad influence on me. Laugh Out Loud

Nice work but I'm a little concerned that you took Vladi's advice. Laugh Out Loud

Well done Fatdog!

Any chance of posting some pix of what parts of the assembly need to be unscrewed next time you have her opened up? The one in my 9494X needs replacing too. Being new to this it's quite daunting trying to remove something in there with any confidence of putting it back together remotely the same without a bit of reference material. Some other threads on this subject were very helpful, but I think I'll need a bit more guidance.


Rock on.

I think I took the pictures, I just need to get them off the camera. I'm in the middle of working on my GF-666Z at the moment and have invented quite a few new obscene words.
