By all means, check the Quad Forum. There's a guy in CA who specializes in restoring Sansui quad gear, including the QRX9001. He did mine about 2 yrs ago and I've been very pleased with his work on both the Sansui and on a Audionics Space & Image Composer. It's not a cheap process, but well worth it! His handle is "QuadBob" and he very knowledgable on Sansui's gear, has identified all the weaknesses in the x01 series and has a way of dealing with them, such as the channel droputs, channel imbalances, etc. The problem is the complexity of the circuit boards used by Sansui, and the pass-thru solder joints on them; the cold solder joints are a notorious problem & Bob takes care of that as part of his restoration. I know your symptoms and can verify that when they first appeared on mine in the mid-80's a local auth. Sansui shop in OH wouldn't touch it, saying it was too expensive, out of date, etc etc. I've had the wooden cover off of mine, and it is a complex piece of equipment, indeed. My advice is not to let a "local" shop touch it, and get some help from someone like Bob who knows, understands Sansui's and is an Sansui-lover.
Bob is a super nice guy to work with and a very serious quadraphile. In fact, he can spend an hour on the phone talking quad, its history, all the equipment, people in the business, recordings, etc.
Here's some contact info:
quadbob@prodigy.net
some website info on him, his restoration and the forum:

There's more on him, do a google on QuadBob.

BTW- I found you post by accident, as I was looking for info on other vintage Sansui gear.
Good luck, and I hope you get it repaired. The QS Variomatrix does wonders on stereo recordings, even compared to new Dolby ProLogic IIx. It's a great receiver!
