Hi Guys,

Has somebody a simple, easy to build tranny matcher for stripboard?
Can't find any, and transferring schems to stripboard is hard for me...

I wired up the circuit here directly to a pair of 4 pole switches.

No stripboard needed.

Do you also have to match the gain? I thought you did, but I could be wrong.

Handy layout, thanks. I think that middle GROUND rail which is going to R3 and PIN3 of the PNP socket, might need to be cut.
