In Reply to: What about tiny DC imbalance? posted by KurtP on March 12, 2007 at 13:40:04:
HA-107 will take 1-2 mA imbalance in the primary. My driver circuit is a pair of 45 with a common cathode resistor. I matched tubes as best as I could, and then compensated for the remaining difference with additional small resistor in one of the cathodes. Due to drift, there could be 0.5 - 1 mA unbalanced current, but I did not notice any deterioration.
