Hi Andy
I checked the original speaker - no output whatsoever. I did connect the new speaker without checking first (numbskull on my part) but I'm pleased to say that its still working (thank goodness). It appears that this version of the amplifier has a ax120 power amp circuit board with Hitachi BUZ901P and BUZ905P so I hope they are not damaged as it appears that they are virtually irreplaceable. I've found this from Award Session who still deals with these amps

so I need to check R9 but its a tiny little resistor to check. I assume I'll have to disconnect one end to check its current resistance.
Best Regards
Rob
