I used this amp for several years in the 80's and his successor (under Reference SRA 2400) in every way possible, I Posed four: 120W x 2 300W into 8 ohms mono.
What I liked most, silent (no fan), its a huge, clean, neutral, dynamic, seamless protection, never failed in five years of use. The least are the hot (and therefore the initiation of protection) when stacking the amps (convective cooling). The problem is solved by breaking the two-rack I Posed.
The value for money was average (expensive to buy).
Having taken over the business, with experience if I find one now OCCAZ I buy it now, for small sound systems or services.
