I've done as Alan suggested and here's the result:-
The time base was on 5ms/div, channel 1 (top) 10V/div showing the signal straight from the sig gen and channel 2 was on 1V/div connected to pin 6 of V3. I could only see a single line at the bottom so what the camera's up to I don't know.
There was a clear sound coming out of the speaker while this was going on.
Injecting RF into pin 2 of V2 produced a noise but not a very loud one.
I'm not doing any more until I've made some space as the current conditions are downright dangerous to be playing about with high voltages in.
