Re: Harry Kolbe Mods
JP / Chris,  
I've seen the inside of one Kolbe amp - one of my customers had him do up his red-knob Twin. Chris is right; an entire dedicated higher-voltage preamp power supply was built into the amp, transformer and all. The amp sounded OK to me, and my customer was pretty happy with it, but it seemed like a lot of work to obtain a voltage that was available two RC-networks back on the power supply rail - must have been a reason he did it that way, though.  
As far as schematics go, I really don't know - it's quite possible they don't exist, at least in 'single print for a single amp' form.  
I've never met Harry, but a few people I know have, and all agree that he's a very knowledgeable, friendly, and helpful guy - you might want to spin him a call, JP (he's in Manhattan, don't know his number but it should be under 'Harry Kolbe Soundsmith').
