I cut the vibrator can and the contacts were not welded but they were corroded I cleaned them up but I still couldn't get any voltage so I played around with the contact arms for the outside contacts and really got this thing vibrating and got it up to 60vdc across the filter cap and around 90v on the plate of the 7A7 about half what I need. At least I'm seeing some voltage so the transformer should be ok, I've been playing with the gap and that really varies the output. I suspect some of the spring has gone from the contact arms I might replace this with solid state unit that I mentioned earlier.
