This thread is for reference for the next time I have to repair a blown line filter board. If a short develops in the transformer or before, the chokes smoke.

The line filter board is comprised of:
2 rf chokes (L406/L407)
4 capacitors (C412/C413/C414/C415)
1 resistor (R405)

The chokes are unspecified in value and are 18.5 turns of 18awg enameled wire over ferrite, add UV resin to enamel wraps and heat shrink over part.

The resistor is 2.2Mohm, the capacitors are 102k .001uF @125V.
