:) Robin,

Thanks for the information. I have noticed that people on the TAN site are always willing to help. I did check the the 5Y3 tube and the glass does rotate slighly with the base.
I spent some time today checking the wiring with the schematic and everythig seems to be OK. Unfortunately I ordered only one 5Y3 rectifier tube. I ordered two this time and now I will have to wait for it to be shipped.
