ok, since it's impossible to use "B+" as a search term and skimming GO-7 threads yielded no obvious answers...
to test the B+ on a GO-7 i know the positive lead on the meter goes on the "tubewards" leg of the large, white resistor. but where do you connect the negative lead? putting it on the a/c neutral shows a half value, but where do i check to find the actual value?
i thought i remembered someone saying you put the negative lead on the chassis (ground) so i tried that. somehow that doesn't seem to work though, as it sparked and lost the picture. both fuses are still good and i'm still getting neck glow, so what component(s) did i likely toast doing this?
