100/50 watt Metro-Plex. George Metropoulos called me to have a go at this amp he just shipped to a customer here that arrived with issues. Both were relay issues, one was a cold joint on the switch at the back of the Boost control. The other was another boost relay that was hanging up and causing real bad tones. Turned out to be the relay wasn't getting enough voltage to fully engage. Seems he had experimenting with resistor values, and upon a couple of voltage checks, had me jumper a 100 ohm feeding the coil. Worked like a charm.
But, aside from those two small things, what a nicely done amp this is! Has some real usable features like Variac/Full Power switch, 50/100 watt switch, FX loop switching, 3 or 4 different preamp modes. It's pcb, but laid out real nice on red board, beefy control pots, just nice. Working for a little bit with George was a pleasure, real nice fellow. It's always nice to interact with someone who really knows what's up.
