I'm going to build a guitar preamp using back-to-back PTs.
My 1st PT has 6-0-6 secondary.
I'd use 6n2p tubes which need 6v at filaments. And I've to go to the 2nd PT with 6v to get the correct HV (after a voltage doubler).
Can I use the two halves of winding to get two 0-6v sources?
I've attached a pic.
Should it work? Any suggestion?
Thanks in advance!

I use back to back transformers often. There are always voltage losses in my circuits.
Ie. For back to back 230/6 trafos I only get out about 210v, not 230v.
This sort of psu is also high impedance and voltage drops rapidly with load. (Makes it safer for newbies - if they touch the wrong wire they get a huge wake up without becoming crispy critters)
So design for higher voltage out than you think you are going to need.

Moving this over to Instruments & Amps (guitar amp questions belong over here) - this issue has been discussed quite a bit in I&A so you should get plenty of additional input- Status
