For how long have you been using it?
10 years

What thing do you like most/least about it?
+: Double channel stereo surround sound ==
+: The power released
+: The sound (ultra-nice)
+: Low profile
-: Fuses that are fragile (I blow a minimum every 6 months)
-: As all the old amps, maintenance (loosen up knobs etc.)

Did you try many other models before getting this one?
No, inheritance

What is your opinion about the value for the price?
No idea, there are occasion from 50 to 400 €
However, this is an amp that I love. A single color, very warm.
I coupled to KLH 2 pairs of speakers (also from the late 70s and in a state ... surprising that they still work, boomers are arch-deformed) and I get a fish in Bass really bluffing!
The whole spectrum is returned with yet in my case (but not widespread on these models) a small dent in the high-mids.

Knowing what you know now, would you make the same choice?
Retrieve old amps: Yes, definitely
