Title: artificial center tap
Post by: ernie_jr on March 10, 2013, 01:00:51 pm

I just got a replacement transformer and it does not have a center tap for the 6.3V heaters. I know that you can create an artificial CT with 2 x 100 ohm resistors. My problem is I dont have any 100 ohm resistors. I have several 120 ohm, 160 ohm and 180 ohm in 1/2 watt ratings. Will any of these work in place of the 100 ohm?
Thanks,
Ernie

Sure. Use the 120's, but any of them would work.
