I had one of the early ones (the Fathom) before they renamed it come into
my shop for repairs. The problem was that 10K 3.75 watt resistor mentioned
above had damaged the PCB by repeated heating (and cooling when it gets
turned off ) so one of the copper tracks had a hairline break in it. The resistor may be designed to work at 175 degrees C, but the PCB is not.
