Help on ancient Audionics CC-2s

Hi folks. I'm a fringe dabbler in audio---now stick to mostly entry-level, as I got cured of my audio addiction after working with Keith Yates Audio and Levinson gear in the 80s, discovering I would never stop, stop, spending or experimenting, so I quit, cold turkey. Yikes.
However, I recently picked up two of my favorite blasts from amp pasts,
Audionics CC-2s for about 99 bucks each, plus shipping, plus whatever repairs/ mods I need. Want to run them in a bi-amping situation. I'm not audio e.e. savvy to do myself---but have an excellent repair shop in my town with folks hip to Audionics, complete schematics, etc. Amps work (one output transistor replaced) but may want new caps. Any suggestions? Black Gates? Thanks much!
