Building or buying an IVR / step down voltage buck converter for the instruments
I bought one from @67fish383S as a spare. Quality piece and he did it for cost.
He's a smart cookie! :thumbsup:
Chknout threads he has started, very knowledgable!
Just contact @67fish383S on here. He makes and sells those on here and has already done the legwork for you. You can look up his posts on here about it.
