hey-hey!!!,
What do you want to know? Keep in mind, these will be semi-experiential guesses, and should be taken as such. +/-15% is about what I expect to be able to hit, with exceptions of B+, cathode voltage. Plate voltage will be dependant on your exact 5687 performance and where exactly you set the active load's current level.I don't have one of these things in front of me to measure and report on.
regards,
Douglas
