repairing dbx units

Does anyone know who can do repairs on an old dbx 224 tape noise reduction unit?

It would probably be less expensive to get one on ebay. I have a 222 collecting dust here.
Gacurt, I am too lazy to dig up the address, but if you contact The Sound Well in Berkeley CA. you will be on your way. Check their site for DBX info. I have a perfect 224 you can have for less than it will cost to fix yours.Z.
There is a 224 on ebay now with buy it now for $39.
