Dear Teemuk, thanks a lot for the link. It´s often difficult to get "modern, commercial" amp schematics on the net. The MG was even cheaper than I thought, it´s very similar to the VS8040 minus the 12AX7, period. I was for ages the official service for Import Music, the argentine Marshall importers, but lately we´re not in talking terms, because of some unpaid bills. I still can´t believe in the skimpy 1000uF power supply filter capacitors. They must have about 10V PP ripple on full power, and the 50Hz hum, mixed with the guitar sound, must be easily heard . And the TDA7293 in no way can output more than 80W RMS , by their own admission (6.5A Pk limits output power into a theoretical 84W into 4 ohm resistive load, much less into a real world speaker). Thanks again.
