Hello... I have a Nakamichi Receiver that has been a pride and joy for (wow) almost 20 years now. Granted, it's needed repairs more than once, but it's well worth it.

So my latest problem is the tone control button seems to be broken such that it causes the volume in the whole system to fade in and out. It's a real drag because I keep the tone either OFF or on and zeroed.

I'm looking for advice, I could:
1) Take it somewhere for repairs. Where do people take these things for repairs these days?
2) I've got it in pieces: Has anyone attempted to bypass the tone control all together
3) Where could I get replacement parts? I suppose I could buy a TA-1A off ebay and use that to replace the tone control board...

Any other suggestions are welcome...
