After replacing since you prob dont have a variac you should use
a "rubber fuse" to protect it. You have many of them, a 75W
lamp. Remove the wire from pin 4 of the FBT. Hang in the lamp in
one end to pin 4 & the other end to the wire. If it lights dim
& you get a small dim pix things are OK for now. If it glows
bright you have problems.........
stop quote.
the prob with just using a dim bulb as you have it (at the primary of the power trans) is if there is a prob in the circuit around the HOT it may still blow even with the dim bulb. I could be wrong though, as I thought these chassis have loosely coupled power trans that should limit the current to some degree. Zeno needs to chime in to clear up.

Well I can jumper the hot and neutral of the outlet and put the hot and neutral of the plug end in-line with pin 4 of T207. That way don't have to undo all whole DBT and rewire it.
