It may be that the contacts need to be cleaned on the vibrator...I didn't take the shell off of it yet. There is a ground wire and an antenna wire, and I didn't do anything with the ground wire, but thinking back, it's not going direct to chassis ground. ie, I don't get continuity from the end of the wire to the chassis itself.  It looks like it may a floating ground. I also didn't have the tube shields on yet, as I wanted to make sure the tubes were lighting first.

My preliminary readings...both with no load...are from the 24 V transformer I get 27 VAC out. With an 8 amp bridge retificer & 100 mfd cap I had 37 VDC.


Need to know what the voltage is under load. No load doesn't tell any thing.
