I am with you there, a PCB makes for an easy build.
As for this one, Looks OK, you can use a verity of 9 pin tubes, and hey. There $9.50 if it doesn’t work for you pull your tubes and you are out two bucks worth of resistors.As for the circuit, I would not have considered building at first look, I being a simpler is better kind of guy. Then I heard it.
Shows what I know.
John Broskie of tube Cad, is coming out with a PCB as well. I want to see it as well.
I don’t know who you mean by "Shannon's site" is this one I know by another name?…John
