Philco 511 Restoration and Questions
#31

Well I made a mistake before I ever completed the RC Couple.


There was no noise coming from the test speaker because I used enameled copper wire to connect it to the speaker post and didn't realize it was acting as an insulator instead of a conductor. The copper wire I used off the test speaker to the two speaker post is enameled dipped, no conductivity on the outside coating. What I fool I am to have just realized this!!!!!!!!!!!!!

As a result because of my mistake, could the 1st AF trans still be good? with that meg ohm reading?? Perhaps I will take away the RC-Couple and try the AF trans again.

I completed the RC Couple on the 1st A.F. Transformer. I double checked my work, everything is on properly. There is sound out of the test speaker. But it is just a cycle hum. No static, stations, or any other noise no matter how I manipulate the controls. I tested the R.F. Coils, all within just a few ohms, good. All the rest of the chokes test good. Could the set be way off on alignment to where it will not pick up any stations?
