I am starting some work on a Philco 80. In a 2014 post, this gentleman mentions:

"Rebuilding a Philco model 80, I used all the advice from Ron Ramirez. I had already rebuilt one of these, so it was easy to remove the second IF transformer to replace the factory 4 megohm with a 2 megohm. Imagine my surprise when I found no 50 mmf in parallel with the resistor which had changed to 6.6 megs. It was easy to put a 50 mmf from my stock but I was amazed that such a radio with a missing part came out of the Philco factory. It must not have been very sensitive. I could tell that no one had removed that coil previously. Interesting mystery."

Is there a tech tip or information on this 4 meg to 2 meg replacement? Or the 50mm capacitor replacement? Should I expect to need to make a mod like that?

Thanks,
