Hi all,
I used to repair Phase Linear products in the Chicago area from about 1972 to 1975. Early on when I called PL to order parts sometimes Bob Carver would actually answer the phone. Repaired mostly PL-400 models but also quite a few 700's and 700B's. I left Hi-Fi repair for a position at Panasnic long before Series 2 or PL's with complimentary output stages appeared. I have carried on my audio hobby to this day and have been involved in cloning Krell KSA-50 & 100's at another group back about 2005 and much Pass Labs gear. I stumbled on an old and forlorn looking PL-700 a few months ago and couldn't leave without it. 150 bucks was a fair price even though the tag said not functioning and the top cover was missing. I brought it home and cleaned it up and revived it, only needed re-capping of the driver board. Main caps had been replaced in the late 90's and reformed perfectly. I was surprised how good a 45 year old amp can still sound. Waiting for my WO driver board kit to arrive. Going to listen to quasi first then switch to full complimentary.
