For sale, my old friend B&K ST 202plus power amp. This fantastic amp was great sounding on it's own, but it was modded by Sound Unlimited in Bristol, CT to be a giant killer. The Mods done were: DC Servo Loop Added
OP Amps reworked for more linear operation
All Caps Replaced(Eliminated Cap in Feedback Loop)Rel-Caps\Rifa\Rima\Siememens
BIAS'd to Class A Operation
Star Grounding
Changed Wires to Kimber
Transformer Replaced with a High Current Toroidal
The issues with the amp are a small "pop" when turning off, so I turn down the volume when I power off. A small hum present, but I heard that could just be the nut that holds down torroid needs tightening. It may not necessarily due to this amp, it could be my old preamp. The hum disappears when the music starts.
I do know when it's playing music, it's first rate, very warm and tube like. The mods also gave it a liquid texture with great detail, much, much better than stock B&K.
Paid over $2500 new for this modded amp back in the late 90s.
