No, I have not modded for 6cg7 but I have rolled 5751s and others and yes I use Westinghouse 7591s- the electroharmonix are actually excellent as well. I have done the 6cg7 mod to other vintage amps and it is worthwhile most times.
I take it you've never heard the the Model 2?
Until then, have fun with the Mc225, your opinion will be different( and not a guess) when you do experience the Marantz-despite the mods to the Mac.
