Quatre Gain Cell Amplifier

I have a pair of Quatre 8000 Series II Speakers from the mid-70's and have been thinking about hooking them up with a Quatre Gain Cell Amp and Pre-Amp. I know about all the stability problems with the Gain Cell and I collect more out of curiousity than anything else. I've never seen the Gain Cell amp before and was wondering if any one has a pic of it. -- Chris
