if it was easy i would say isolate B+ and load it with a 40W 240v lamp-bulb,

of course being a G07 it is not easy, so maybe you will need to cut a track.
if you have a japanese copy then they (being smart) added a link you can lift to isolate the B+ line!

with B+ isolated and loaded you can check the regulator is running and ajust it for 120v.

if you get this far then ring the LOPT and suspect any secondary diodes.

let me know the progress, my repair ratio of G07s to vector stuff is about 20/1.

Btw. in about the last 20 years i have NEVER seen a G07 transformer fail!!!!
