You don't need a rectifier. At least, not for the heaters. As long as the source has enough current to handle the heaters of all tubes.
To get 400+ VDC. You start with 6.3 VAC for heater/anodes of the rectifier and at least 400 PIV AC on primary line. Then, rectify it to 400+ VDC. Right?
Hi FL, i was wondering about the feasibility of using a voltage doubler on the 6.3v filament line and getting 12.6 to run 12x4 rectifier. But it was pointed out that i would lose 1/4 of the current in the circuit.
I'm not familiar with how to double 6.3VAC to 12.6VAC. Not without putting another transformer inline.
I don't know if the voltage doubler circuit will exactly double the 6.3vac into 12.6 VDC. Eli, says it won't be that much, but i guess i should breadboard it and see what i get. I have all the parts and i will put it together and let you know. regards.
