Hello
Since I posted the above, I did some research, using a web site suggested by Ron R. It is a tube data/pin out site.
It looks to me like an 80 rectifier tube can be subsituted for an 84. The operating condictions and characteristics are very close to the same. It also showed a typical full-wave rectifier circuit, and it shows the field coil lead hook to the filiment. So I think I will use the caps and resistors called out on the schematic.
Anyone have a thought on this?
I would still need to replace the open winding output transformer. the Philco # is 32-8053, is there a sub for it.
Sorry about the first post, after I read it again it is a little confussing. Icon_razz

Thanks Bob
