   Thanks for that information, it is very helpful.
   I still have a question about the value of the cap in question.. on the schematic it is #80 which says it is a .03 uF.
   Maybe I am looking at the wrong block, but in tracking the wires   from the heater of the rectifier tube I get them going to a .o3 cap , #80 [ on the schematic] but in that block it tells me that there are .05 caps in there.
    I feel that I am missing something here.
