well....yeah....is a nice mixture of C audio/HH lateral mosfets,and sounds just about the same,not sure about the rated power,as i don't have the testing equipment with me here,and the amp claims to sustain 800w rms per ch in 4R loads,judgeing by the number of dual die fets it can without problems....but judgeing by the psu transformes that are rated 800w.....hmmm don't think so....Confused in the best scenario with 800w rated transformers you have maximum 600w rms on outputs Confused but no way from two 800w transformers to get 2x800w on outputs...what the hell....am i missing something here? Confused

The amp internals does have that C-Audio vibe to it, the PCB layout looks like the Beta pro 800 series & the transformer on this amplifier is also been potted. Wink

technically magnatec but both semelab and magnatec were interchangeable for a while when they merged. The semelab logo still incorporates the 3 arrows if you look carefully

That Macro reference is a gorgeous amplifier, just look at all that space inside for non-custom, not ruinously expensive,  replacement main filter capacitors… :D

I think this MT1200 had a hard life as i'm pretty sure crown didn't fit those parallel resistors there ConfusedConfused i've seen those resistors blown in a Macrotech 1200 that had a faulty in the driver board as far as i recall,the resistors gave up to save the outputs,the fault was couple of TO92 transistors next to the input sensitivity three way switch.

You don't need to be impressed by the MT series mate,this are proper overengineered amplifiers,you just need to adjust them,clean them,make the solderings again and you have proper bulletproof amplifiers for life,that Macro Reference is a beast...as i was saying before....deep bass = loads of silica dies on heatsinks and proper psu....now i've seen it.ClapClap
Mmmm funny i must say,i never adjusted the ODEP voltages on any of my MT-s so far,just the bias as it was way off on all of them,however never had any problem with odep so far,how was the ODEP on yours mate?
