Considering doing the Plexi 100 for my next build. How difficult is it to go from the 50 to the 100 as far as modifications to the schematic? Sorry, haven't really given it much of a look.

It's easy. Just look at the 100 documentation. Don't look at the 50 docs!

The schematic is the same as far as the board goes
A 100 watt amp just has two more power tubes
The feedback resistor may be different is all
The power supply is different on 50 and 100 watt Marshalls
Go to the library page and look at the Plexi 50 and 100 watt documents

I see now. I was thrown off by the number of 50uf/50uf/500v caps but I see that it becomes clear when looking at the power supply information. Thanks!
