Carver M400a Power Amplifier

It was with some trepidation that I looked at this - it was dead. Having just looked through the service manual I was thinking ***NO*** anyway it's complicated in a Carver kind of way, as it turned out the fuse had blown in the plug, the fuse in the unit looked worse for wear 15 A! Approach these with caution as there is a complicated set up as the +/- voltage rails are switched in and out depending on the power requirement, a triac fires through the mains transformer to provide the supplies\regulation.
