I went with 10W cathode resistors which were tricky to fit onto the board but I had the amp disassembled to install a 50W output transformer anyway. While more dynamic and clearer, even with KT88s and the Plexi-style OT, it still sounds and feels like a Rocker 30. Neither the tubes nor tranny changed the actual voicing of the amp.
Thanks Stymie.
