One of the better amps of power amplifier STK (STK 461).
Beautiful warm sound.

re: AM-U01

Very good sound, even under heavy load, always. Quite hard to find these days. Power output is so nice and linear, I find it hard to believe this is rated 'only' 22W rms per channel. You could fool blindfolded listeners in believing this is a class A amp.

re: AM-U01

In need of service manual for this amp.
Seems quite difficult to access circuit boards.
Can you help?
