680V? Really? I glanced at the bias calculator page and 600v is the highest listed. Are today's tubes rated to take that voltage? Will biasing way down work or can I knock the voltage down somehow?
BTW, I'm measuring voltages without power tubes installed. This one hasn't been up and running in a while, so I wanted to check it out. Should I expect a voltage drop with the tubes installed?
