That answer is simply not true. Power supply is DC current. Tubes are biased at DC current. When you feed the power supply through the center tap of a push-pull transformer you are supplying DC current to the transformer. I guess maybe I should reword my question. How much DC bias current can the primary winding wire handle per side (per tube) at the primary's maximum voltage rating? I don't want to flash fry the primary winding by simply turning the amp on. Even Hammond supplies max DC per side data for their Push-Pull transformers. For example the 1650P 6,600CT is rated up to 200 ma DC current per side.
I am building an 100 WATT Push Pull amp with CXPP100-MS-10K, I bought from you a couple of months ago. I have a some confusions regarding using this OPT. What is the maximum D.C it can handle at its primary from C.T to Plate ? What wire size is used in primary?
