Fuse blown during use

<< < (2/2)

Paul Birkeland:
I would suggest posting photos of the area around that terminal strip.

I have never had a new capacitor that wasn't good right out of the box.

fullheadofnothing:
What value fuse are you using?

slm:
Ok So next attempt  :(

The fuses are 1.5 amp slow blow

I have completely rebuilt the voltage doubler - new caps new diodes , new resistors new tag strip.

Still blowing fuses

Have taken photos during the ( 4th ) rebuild as I add the diodes and the caps . I also rewired the heater supplies just in case .

Without the voltage doubler attached the fuse is fine the secondaries on the transformer read a little high but otherwise as expected . With the doubler in place the fuse blows immediately . it is not attached to the rest of the circuit except the ground wire . I cant see a mistake .

Paul Birkeland:
Can you double check the AC voltage on the high voltage terminals on the power transformer without the diode attached? (See bottom of page 33)
