Mute-relay modification
A modification involving improving the
switch on/off threshold of the mute relay
was introduced shortly after production
commenced.
This involves the changing of resistor
R46, initially fitted as 100kR to 200k or
220kR. It is not practical or necessary to
remove the PCB, and the fitted resistor
can be cut out, and a substitute resistor
carefully soldered in it’s place.
