Re: 7834 High Voltage Board

Next thing to try is disconnecting the input wire to the x4 voltage multiplier. Then connect the two
coax feeds. If the main supply then comes up OK, the fault is with the multiplier. If it is still in
tick mode it is likely the transformer.

Craigs

I disconnected the multiplier and the other high voltage secondaries. Still the power supply shuts down.
