Let's Repair and make Safe this Mesa Boogie Mk I - Part Two

Описание: Let's continue the Mesa Boogie Mark 1 repair. We will start with correcting the dangerous mains wiring, then take a closer look at how Mesa can make their “No Bias” promise. I’ll explain what crossover distortion is with one of my great analogies (“Enough with your analogies, Dad!!”).
Let’s then Bias the unbiasable (yes, it’s a real word) Mesa. You’ll learn about a common issue with Mesa amp's intermittent signal which can also be relevant to other amps with Send-Return loops.
When I think of Carlos Santana, 2 things come to mind: His Mesa Mark One and PRS guitars. So you get to hear the Mark One with my PRS Santana guitar.
