The only place I found the schematic is in the 1941 Bateman book page 52. Acopy is at the following link in djvu format. You will need a djvu reader to view.
The schematic gives different tubes than what you list, so these tubes may be the newer number for the old numbering your tubes have.

According to my Mallory Radio Service Encyclopedia, the Information for GE J-105 says to see RCA 76 or RCA 77. The RCA schematics can be found under resources on this site.
Those RCA Schematics have your exact tube lineup.
Doug
Thats RCA R-76 or RCA R-77
That sure looks like the right schematic. Thank You for all your help Doug! Sincerely, Kevin
