Not sure you are checking the right " G-1". We mean the G-1
of the hoz out tubes. They are in // to give enuf output.
Typical sets draw abt 210 ma this one IIRC 240, beyond most
hoz out specs. Thats why 2 HOT's. Others did it in the early days.
Admiral did & if you changed the FBT there were pages to mod the
set to use one 6KD6 H out NOBODY wanted to do them.
If that neg voltage is not there the tubes stay on too long.
See class C amps. !
Once one fries the other takes over. That one will overheat trying
to supply the HV but one cant keep up current demands.
Bottom line is without the proper G-1 voltage you will cook up expensive sweep tubes. Fix that FIRST if needed !
enuf fer now
