I have two of these nice amps, true they are a bit sensitive and run hot if pushed, but have worked well since the early 80's for me. They don't enjoy low impedance and the on and off switches have been broke in the on potition for quite some time. I have just used a on/off switch at the outlet.
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.
