Added 100K pot, top right, to adjust the square wave amplitude:

Around 1 volt peak-to-peak going to the amplifiers:

But the square wave output from the signal generator is 12 volts, and can’t be adjusted:

A bit of a game with the case, and sticking buttons, but got there in the end:

Step 1 – connect 9 volt battery – Good. Nothing getting hot. Set jumper to 100-3Khz
