Thanks, 12SK7 it is. That is strange how my mind messed up the two series 
and let 35W4 be octal.  Even after reading your post, the 35Z5 refuses to 
come to my mind, as though I had never heard of it.

The linked article says that the chassis may be connected to one side of the 
line - I don't think I ever saw that happen in practice on a radio.  I don't 
even know haw dangerous a 120 V power line really is to a healthy teenager.
