Alesis M1 Active MK2 Power Supply Schematic
Anybody got one? I got a dead PS on one of my monitors, and Alesis
wants $90 for one. Since the monitors are a total of $350 per pair....The -36V rail voltage is all over the place, while the other voltages seem fine. Anyone work on one of these? |

Alesis M1 Active MK2 Power Supply Schematic
I wish it were a line frequency transformer. Wouldn't need a schematic
for that. It's a switcher and I don't recognize the chipset on this switcher, unlike the behringer ones I've ripped apart. Eeyore wrote: wrote: Anybody got one?

The latter are easily fixed with routine knowledge. Graham |
