Does anyone has schematic of the meyer sound amplifiers? This class AB/H with mosfets seems interesting.
No schematic's for Meyer Sound, if an amps fails you have to replace the complet module, a little contrary to John Meyer's hippy background, a UPA amp module will sets you back 1200€, despite the fact just one IC was causing the problem..
That amp is based on IRFP9140 and IFRP140.

Hi Justanalogue do you have some more pics of overall board and some zoom in on the ICs.
Btw at what voltages are these amplifiers running?

No, that's all, and I don't work there anymore so this it, all I know is that Meyer uses Meanwell PSU's, SMPS as far as I could judge running on 48 Volts and 15 for the control board.
No idea, but both parts use the same amount, the woofer is 2 Ohms impedance and the high driver 8 Ohms.
