Cornford MK50II rebuild
I build the MK50 II last year. The Amp is working fine.
Some people asked me for the layout and the verification fot it, but I'm the only one who build the monster yet. So I'm looking for some volunteers to check my layout.
Cheers, lhd3000

The phase invertor looks like it has a cap going from plate to plate [ seems purposeful , is that correct ? ]
I haven't looked heard at it [ or heard a real Cornford in person ] looks to be a fender clean and marshall like o/d ?
can you describe how it sounds? sort of ? thanks

The cap between the plates is completely correct.
As you have already said, the clean channel sounds more like a fender, the OD channel is more soldano, but with a good bassrange, also endless sustain.

The cap in the pi is to stabilise the NFB loop. There are better ways to do it but this is the most common and it's found in nearly all Marshall inspired circuits.
