DC heating for 6SL7

[umenn]

Since the EDCOR XPWR005 has two 6.3V windings are there any pros to connect each of them to a separate 6L6GC tube?
And what is the correct connection if we want to get 12.6V for a DC heating for the 6SL7?



Sorry for this Paint draw..

Use two bridge rectifiers one for each 6 volt winding and sum the output of the bridges in series and you will get enough voltage to regulate it to 12 volts , use a separate 2200 uf 25 wvdc cap on each bridge .

Thank you.
You mean something like this? Looks good for me. Should I ground the DC circuit somewhere?

That should work fine , you can't ground the 6SL7 because of the 0ther two grounds . Use a .1 uf cap off the negative end of the filament of the 6SL7 .
