Thanks Al,
No-one responded to my description of the circuit (#10), or my subsequent question in post #13. However, having read the description, it looks like my initial supposition (about the transistors being an SCR rather than an oscillator) was right, and that the values of those capacitors are chosen to respond to 10 pulses. That's reassuring, I guess...
It feels that we're pretty close to finding the culprit. I'd love to see the pictures so that I can understand just how difficult the mechanical issues are.
All the best,
Mark
