Ive also had a rash of antenna-coil probs recently! They were definately bad ( fully open)! However, sometimes we all forget checking the other things possibly causing some of the intermittent probs. I know I do!! Most of you techs here are "light yrs" ahead of me restoring these old Philco sets, period!! I have learned sometimes that going back over the tube-socket pin connects, tightening them carefully with needlenose pliers, running a tube socket cleaning brush thru them carefully, and adding abit of new-solder to the tubes pins-tips connections, and scraping tube pins clean with a exacto knife, can sometimes yield good results in ALL these old sets for ridding intermittent probs.Also, make sure there are no "cold" solder-joints on any of the IF trans connections! I just ran across this prob recently also on a Zenith. Go back over and add abit of new solder to insure good connections, and remember the tube-sockets pins connections can "never" be too-clean. Sometimes, our tube-checkers sockets are tighter than the chassis, but then again, tube checkers can Lie also! Even the Best ones!! The "best test" for any Tube is in the set it is designed for! Just tryin to help.
