Having the same problem as George. It seems that there is a slight boost, but barely noticeable. And even with a transistor out, there is still a faint signal.
If that’s the case, could it be you’ve got the off-board wiring wrong?
It does not work for me. It sounds the same with or without the circuit, and I get audio thru even without battery or without transistor.

Verification much appreciated, Earplane 🙂
Verified and working inside a 1590A.
