Hi Im just about to install anew diaphragm on my 813B but is it just a case of taking out the three screws at the rear of the unit or is it a lot more involved?
Whilst the units are out is it a worthwhile mod to replace the old connecting wires if so whats your recommendation?
It seems the input has to negotiate fuses and bulbs !!!!
Is it a worthwhile mod to bypass these?
Thanks
Dave
