Yet another broken VCR

That is a line filter dual choke. The two power cord wires go through it's two windings....Which have just enough inductance and are 180 deg out of phase so that frequencies above 60Hz are attenuated.

It will feed a diode bridge, that then feeds a XXXuF 160-450V cap, that then feeds a switching transistor, that then feeds that bigger high freq transformer that then gets rectified and regulated to PS B+/- rails....

First make sure you did not short or open that choke. Then check the bridge and cap for shorts....Beyond that and cap changing I'm not all that good at SWMPS (switch mode power supply) repair.

There is an error in your post: most sane electronic techs, don't jumper a blown fuse...They pop in one 150% of the amperage of the original and see what happens...Unless they don't particularly care what becomes of their gear.
