Interstage transformer problems
#3

The voltage measured with a DMM is and has always been -59V on each grid, measured from filament. The caps were replaced twice, both times with new metalized polyester tubulars, same capacity as originals except 630V and mfg was Mallory. The .13 was made with a .1 and .033 in parallel. Sockest were completely cleaned, in rebuild, by hand, so no carbon tracks and yes, the same half was open all three times.
