To keep a long story simple, the new distributors of Musical Fidelity sent me a replacement V2 board - really everything but the can and power supply. Plugged it into a power supply and voila, it worked just fine. Come today I plugged it in again to give it a listen, everything fine, and then nothing. The LED is lit, but the tubes are not. Could have been static(the unit is not yet in a can), but obviously some thing died. By the way, there was no noise, pop, fire, nor that smell of electronic death.
I'm going to run this by a friend who has better diagnostic qualifications than I do, but I thought someone here might have an idea what part might have given way.
Thanks, Jon Denver, CO

Check this first Jon with a multimeter set to DC
SK1 (the 6 pin connector on the PSU board) you should get close to these readings:
Between pin 1 and 6 - 12.6V Between pin 5 and 6 - 38.0V Between pin 4 and 6 - 12.6V Between Pin 1 and 2 - 25.3V Between Pin 2 and 3 - 25.3V Between Pin 3 and 5 - 25.3V
