Greetings guys. I am building an amplifier around a GS35B. Recently I came across the schematics of Heathkit SB230 using a passive network to the cathode , doing away with the ubiquitous PI and the need of a cumbersome switch.  The solution is very tempting but I wonder if is there a catch? Any advice will be wellcome
