I was recapping my 38-9 tonight and as usual I check all my resistors.  One I could not find.  It is the (#20) 51K resistor coming off sec of the 2nd IF can to the input of the Volume pot.  I could not find it in the diagram or my radio chassis. I did resistance check between pin5 of 6J5 and the (#21) .01 cap at input of Vol and got 72K.  So I am guessing it is possibly inside the 2nd IF can and drifted high. I tried to remove the cover of the 2nd IF and it was NOT coming off the IF stack.  Before I start REALLY going at it I wanted to make sure that resistor IS inside that can and the cover should be removable.

Here is schematic file:///C:/Users/Todd/AppData/Local/Temp/M0013262.pdf

Did a 38-9 not to long ago, and I believe it's in the can. Just pop it off and look, I'd say.

In the parts list, it says #20 resistor is inside #19 IF transformer.

Interesting. The parts list says the value of resistor #20 is 51,000 mmf. Must be some sort of new terminology that Philco thought up

Most Philco sets had that resistor in the last IF can, until they started using the smaller Automatic "K-Tran" transformers in the late 1940s.
