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!

...so you need to check all 4 tubes in tube rectifier bridge if operational?

@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.

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.


czarivey,

Do you think your two triode ideal approach might explain why the manufacturer of my phonostage utilizes two 300b (or two 2a3s) as rectifiers in the power supply section?
