How about using four
rectifier tubes
like 6AX4 to create a
full-wave bridge?
Converting Solid State to Tube Rectification on a Preamp
I am looking to convert my Preamp from a Bridge Rectifier to a Tube Rectifier. Any members have done or knows how to do this. Your help are much appreciated!

@zipost Do you have the schematics of your Blue Circle 21 preamp? and what is the B+ voltage? BTW, I also found a BC21.1 with outboard power supply on usaudiomart. http://www.usaudiomart.com/details/649027319-blue_circle_211_tube_preamp_with_bcg31_power_supply_fre... |
So, it can be done, the question is why you want to do that! Well, if it's to me, than perhaps I can assume some degree of masochism as tubes get blown over 10 times faster than diode. I think the best bridge approach with vacuum tubes can actually be done with 2 triodes as each triode can be represented with equivalent 2 diodes. |
