Tīmeklis2013. gada 23. sept. · With the two 6V6's stacked and paralleled, you have 0.6 + 0.45 = 0.95A draw. To drop 2.4VAC (15-12.6) at 0.95A requires a 2.5R resistor at 2.25W, so make it a 5W. This doesn't sound too bad, just two resistors of relatively small physical size. I wouldn’t recommend going to a DC supply for the entire filament string.
