Hi Dan, Sterling
Checking the resistors and swapping out tubes was next on the list as it seems to be a heat related failure. Have to find a better schematic first. Sterling ,Yes I tested all the tubes and they test perfect on my tester, however I’ve read that this kind of problem can be a failed tube that tests perfect and doesn’t appear until they get hot. So, I’ll start with the tubes first one by one since I’m sure I have some of the same tubes in my other Philcos, but I haven’t looked yet.
