philco 80 jr. help please. 1st time restoring a radio this old
#45

Your not lost Matt, just trying to follow all of our ideas. I'm glad someone recognized that cap as a 10mfd on the N/A schematic. I guess there is a little of my mind still working. You do have the radio working. That is important. I agree with Mortzh in that don't mess around with changes unless it is working. I would try a 10mfd cap with a clip in just to see what happens. Nothing is going to blow up, put the positive to ground and the negative to the other two. A low voltage any where from 50 to 160 should be fine. Sorry I was looking at the N/A schematic and perhaps not the proper version of that radio. Not knowing anything, it appears that cap is to filter some small negative voltage generated as the center tap from the transformer is "floating" a bit above chassis ground by the resistor to ground. What do I know? NADA!
