ok thanks for your reply.

i need to do something for volume control.

i am ashamed to say a few years ago.... i bought a relay based vol control based off of 1.7.
it was before i knew better, or what a 1.7 pre was. just that it did what i needed.
i have sence trashed it. to bad i didnt know before...sorry.

but these might fit the bill

the control2 board can control both motorpot or a relè based solution
that P1.7 based vol control was from jims audio i guess. his take on P1.7 is unbal.

Why not use Nelson layout on BZLS article , just delete Negative supply part.
