Question Regulated Dc Question

Hi,I'm building a 6sn7/2A3 SE amp and was wondering if it's possible to split the filament supply after the bridge and cap to use 2X LT1086 as current regulators for the 6sn7's.Could anyone help me out with a schematic.Thanks in advance

That's what I drafted (the scan is not so clear ...) today for a preamp I am planning to build. You will need to adjust the 0,5R sense resitors to feed properly your tubes. I think it will work ...

Are you going to series connect the tubes or what??

Ciao

I was planning on using a toroid with 2 0-9v windings .One for each valve(6SN7 linestage).

Well you can series connect both the valves and feed them through just 1 regulator.
