Huge head room, via true mono block construction. 45 watts that sounds more like my Yamaha CA-1020's 120 watts.



re: SM-3636H

A magnificent bit of kit from the late 1970s. I have 2 if these and a SM-4646H to tri-amp my optonica CP-5000h speakers. True dual mono block construction amps feeding 28kg speakers with woofers suspisciusly similar to those in the much admired Yamaha NS-1000s. All at a fraction on the price.

Sometimes not running with the herd pays off :)
