Quad 33, 303 Upgrade/Repair Servicers

I have both a Quad 33 preamp and 303 amp, which I hadn't tried to use for several years. After a recent move I decided to unbox them and give them a try. Unfortunately I guess I had forgotten that there were problems, specifically I'm not able to get anything from the left channel without a lot of messing with the controls. There is clearly an issue and it may involve both pieces. I tried the 303 alone with another preamp, and while it seems to function to some degree, there is still a problem with a tilt toward the right channel. Using the 33 and 303 together, the problem gets even worse and I can't get much of anything on the left.

Now to my main point: there are several listings on ebay for people who offer upgrade/repair services for these and I'm wondering if anyone can recommend one. Several years ago I had sent the 33 to a guy in suburban Chicago, who did some mods, but after several months the left/right channel imbalance reappeared. (By the way one of those offering their services seems to be in Romania and that's out of the question.)

Thanks for any information.
