There are two small fuses on the KLM-370 power supply board.  Be sure to 
check those.  They are 1-Amp, 250V miniature types as found at Radio 
Shack, etc.  They are not the 1-1/4" version like the mains fuse on the 
transformer board.  Make sure both of the KLM-370 fuses are good-- if the 
power LED on the KLM-370 lights then at least one fuse is good, but both 
need to be intact to operate the rest of the machine.
