I have just finished building this preamp and the Marshall 50W power amp. I used 0.6W resistors throughout (except where marked otherwise). My power transformer kicks out 280V AC (no load) which translates to about 350V on idle. I didn't have a center tap so I had to use a full-wave rectifier and do a bit of fiddling for the bias circuit (with the help of Bruce on this forum).
Works very nicely too!
