My MT15 served me well for the past several year, but the other night while playing, the amp suddenly lost like 90% of its volume. both channels sound unhealthy/distorted in a bad way. I swapped the power tubes with known working spares; same issue. tested the bias, 0 mV. couple days later tried it out again, same issue persists. anyone have any advice? thanks!
