[QUOTE="marantz123, post: 1172393, member: 16849"] Hi Budgie What may assist with this is the pics of the monoblocks internals, whether two or four output mosfets, as they were produced in two power ratings, 250W and 125W iirc. Some research reveals that for the mosfet power transistor pair in these amplifiers, 100mA bias is a ballpark, maybe a bit higher but I'm no expert on this amplifier and hoping that forumites with the knowledge will contribute here. The transformer rating is also a factor towards what the amplifier (power) should be expected to produce aside from the mosfets. Thanks and good luck with it. [/QUOTE]
