Today I attempted to install an efb board following as closely as possible to the "modifiy the fisher 400 with efb" forum. I followed the schematics as close as I could also looking at pictures as well as I could to make sure things were in the right spot anyways, I fired up the receiver and took a voltage test, everything was out of control, smoke started coming out of one of the can caps? anything noticable from my pictures where do I start to track this down?
wires from efb are
color "EFB board location" - connection location
green and black tape - ac winding
green - ac winding
black with green pair - ground
red and black tape from 22uf and stf10 - output screen grids
red from 4.7ufcap - 330k grid resistors
black with red pair from 1.8k resistor - CR2 bias supply
