dc and ac heater supply in Aikido

Jaap · 7th March 2010, 04:35 PM

Because my 6,3 volt tap on my transformer has not enough power I am forced to use another tap (5-0-5 volt) for the second tube in my aikido (ecc40 + 6N6P).
My plan is to make a voltagedoubler on the 5 volt tap and rectify this with a simple bridge and CRC filter.

Now I have to refer both the AC heater of the 6N6P and the dc heater of the ECC40 to B+. Can I use one and the same voltage divider for both DC and AC supplies ?

Sure, as long as what you refer to as "another tap" is a separate isolated winding from either the same transformer, or an entirely different transformer.
