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!

You need to use a center-tapped transformer with a 6x5 to achieve full-wave rectification. 
How about using four rectifier tubes like 6AX4 to create a full-wave bridge?

...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!
