Philco 48-200 alignment questions
#1

Hello Philco people!

I have a 48-200 that definitely needs alignment, but before I get the alignment tools out I just want to make sure I'm understanding what the service data is saying. From what I'm reading it's saying for the 455 adjustment to connect the output lead of the signal generator through a .1mfd cap to pin 6 of the 7AB tube and the ground lead to pin 7 of the 14A7, am I reading that correctly? Also can anybody suggest using something other than a .0001 mfd cap for adjusting the high side of the dial? Thanks.
