Hi Stu,

Yeah, sounds like it could be the same problem as before - the output protection resistor, though in the A-171's case it is already lower (at 220ohm) than the 1k in the A-170. So, you could try shorting it, or putting a 100ohm across it to reduce the value, and see if that helps (but heeding Dieter's warning in message #15764!).

Assuming your module is the same as mine (it uses a CA3080, so presumably will need a re-design to use an LM13700 at some point...), it is the red-red-brown resistor on the left of the three between the two chips (i.e. nearest the bigger chip - I can't make out its actual 'R' number).
