Some of these FBT's plugged in. The connections would toast up.
Also the mother board & module connectors went cold a lot. Dont forget the frame grounds.... It doesnt show one but this is about the time they switched to 4-lead caps. An open leg will kill the HV. The SCR is for HVSD. Pull it to eliminate BUT use a variac, you may have too much HV. Start it at abt 70VAC. With the tripler input unhooked you should get a healthy 1/2" arc at the FBT out. These were not FBT eaters. Only ones I changed were badly burned from the bad connections. 73 Zeno LFOD ! |

I checked the Thordarson number, looks like their part # FLY-462. I didn't see on in my stash.
