Thanks guys. Having mulled this over (again) and was thinking, would it be more feasible to use simply 2 of the existing Marshall boards in a bridged design, lowering the output - my thinking is that the heatsink and fan asssemlby would be sufficient for cooling a single IC.
In terms of sounds, I haven't used the amp in donkey's years, I figured I'd get it working and then look to mod the preamp stage (if I can work out something more akin to a hot rodded JCM 800 I'd be happy - though channel 2 does an almost credible job).
