Ross Systems Mega Amp 800



Ross Systems Mega Amp 800

This power amplifier drove my Bose 901 Series 1 speakers for many years until being replaced recently by a Rotel RB-1572. Providing 400 W per channel into 4 ohms, it has plenty of "grunt" but the traditional massive power transformer has a faint hum that became a nuisance when listening at low levels in my very quiet environment.
