As I recall this had to do with how Jerry reportedly (Healy) only used one side of his MC2300, at least for a large period of time, and also mismatched the impedance of his cab and the McIntosh output taps. The McIntosh has an autoformer output so that the power transistors themselves see a constant load. Jerry supposedly connected his 3-JBL cab (approx 2.7-Ohm net) to the 2-ohm taps. The impedance math suggests that this would actually be providing about 225 (or so) watts to his speaker cab. The theory continues to suggest that if he was pushing the McIntosh to where it began to max out and activate its peak limiter, this whole action would be happening with a peak limited max power range in the low/mid 200 watts arena. This would have let Jerry just bang away on that amp setup and it would remain pretty clean and protected, maybe with some limiter dirt.
Hey, I just realized that connecting an 8ohm and a 4ohm speaker in parallel = a 2.7 ohm load.
2x12's can equal 3x12's.
