Remarkable, full, balanced sound from a very modest-looking amplifier. Drives 4 ohm loads with ease and has been the single most reliable piece of audio gear I have ever owned and perhaps the most enjoyable. A lot of empty space inside the steel case seems to help with cooling, as does the massive, raw aluminum heat sink. Very simple build, incredibly easy to access the boards, extremely high quality amplification, especially at low level listening. Solder joints look factory fresh, which may also contribute to this bone stock amplifier's reliability. Brown switches look tacky but are actually very durable and well-made. Volume gets very loud, very fast.

I have the Scott 420A since the 70ties, great sound with Tanoy lancaster gold monitor. Never had any problem.
