My new amp project is down to selecting OPT trannies and I am torn between 3.4K and 4.5K options for my KT88PP circuit. I know that the 4.5K will have a little lower distortion and that the 3.4K will provide more output power. What else is there to consider between my choices for a KT88 PP amp?

TIA
