Hello gang! I have a Drake L7 and 2 power supplies. One shows 2700 plate volts, when driven with 65 watts, amp puts out 800 watts. The other one will do 3700 plate volts and will do 800 watts with 35 watts drive. Will the latter harm the amp in any way? Is 1750 watts at the plate too much for the two 3-500z tubes? Thank in advance.
