Thoughts on the Vintage Adcom GFA1A 200WPC


I always used medium powered amps from mainly small British companies(Arcam,NAD,Creek).I recently purchased an Adcom GFA1A power amp for $140.This is my first power amp over 100wpc(200wpc).I replaced the caps and added binding post's.What kind of sound character improvements should I hear over my trusty 50wpc Arcam Alpha8p power amp?Also,does this amp run class A,reason me asking is it has full time fan regulation.

I have a GFA1A, have had it for about 21 years. Solid as a rock, great sound, no issues that I have been too critical of. Have had to get it repaired 2X by Adcom in its life. I am powering some NAS Squire speakers (North Dallas company back in 1980's) and have been very pleased with the setup. I'll agree with Sean's comments on running hot when cranked up - you better turn the fan on high speed of at a decent volme level. Idle Power consumption is spec'd at 100W per Adcom's original specs (still available on their web site)
