David are you measuring the voltage off CR4106? If so that should be 140 volts that goes to the HOT. It could be C4107 or C4105 on the 140 line. Sorry I forgot my sig line on previos message.

I thought +B was 140VDC on this chassis. Could the extra 10VDC cause the HOT to fail after 30 minutes? Thanks in advance. David Lessard Alexandria Electronics 50 Harrison Street P.O.
