Jack,
I would stay with the 55-70 volt modulator current leaning toward the
high side. I try to set mine at 65 volts. I would also put the output
leads from the modulation transformer back as they were. If you haven't
replaced C69, I would. It's unlikely, but I would check C66 - C68 to be
sure you don't have a leak there.

First I swapped the tubes to no avail. I then swapped the wires and
now have a strange buzzing that I can not locate but it shows up on
the audio with the gain at zero. Don't know if I barfed something up
or not ...
