I am currently on a new build and want to convert the bias supply to two independent supplies. Included is the current layout for the bias. Can anyone suggest how to split this for two independent bias supplies?

Thanks in advance

Here is what I use and it works great in a 2203

Thanks for the info. What voltage supply do you give the circuit? Any schematics out there?

THanks

Welcome Bonsaimaster! I'm gonna try the same dual bias setup, from the SDM site, in my 1987 clone. I can't remember the incoming voltage but that is just your standard Marshall bias circuit that has been split into two identical circuits.

The circuit you have there is much more like a Hiwatt bias circuit.

have a look here and you will see what I mean:
