Just a quick write up of a fix I applied to my WG6100 deflection board.

After switching on Tempest after about 5 minutes the picture was dead and both F100 and F101 were blown.  I tested the diodes D100 to D103 and found two were bad so replaced those.   Switched the game on and the spot killer was on and only the positive voltage LED on the LV2000 was lit.

I connected my meter, black to the ground point at the centre of the four diodes and red to pins 3 and 6 of connector P100.  Pin 3 measured +26v, -26v was missing on pin 6.  I checked the voltage on the red and black wires connected to the LV2000 and both read +33v and -33v.

Replaced the LV2000 and all is good again.
