I now have a pilot light (1100) that lights but as soon as I bring up the variac past 15-20 volts the bulb burns out.  I found the right pins for the filaments on the rectifier 35Z5 but I had filaments only for awhile until I decided to solder two disconnected wires which I thought were wrong:  First I moved R204 to pin 8 (50A5) because R204 was burning and R102 back to it's original position off Pin 8 (35Z5) along with one of the positive legs of the electrolytic.  In any event, I have a light acting as a fuse but still no filaments. Both tubes appear to be good.  Any help would be appreciated.
