In your manual, there is a diagram showing tube locations, which are then identified in the parts list. In the event your manual is missing pages, it may be found as the first PDF file here:
I see most of the tubes match and are in the correct positions. I see
differences with these tubes between the manual and what's actually in the
radio:
V9 & V10 are both 6CL6 in the radio I have instead of 1614's
V11 is a 5V4GA in this radio instead of 5R4GY (both are rectifier tubes--OK?)
V12 is a 6AX5 instead of a 6AX5GT (probably OK?)
I won't get to look inside the VFO box until I get the radio back out but it's
probably got what's supposed to be in there.
I'll need to know if I need to change V9, 10, and 11 to match the manual. I am
pretty sure a tube suffix like GT doesn't normally have any importance with
backward compatibility but let me know if it does.
I'll look at the other information and save it for future reference. I'll also
get the weak resistor in the VFO box. Is it the 56 Ohm one or the 100K one in
the schematic around the VFO tube?
