OK, you guys were right, again
#1

The tube socket for the 80 tube was bad on my Philco 18. So for curiosity sake, after I removed the socket I removed the rivets holding the 2 wafers together and inside between the 2 high voltage lugs was a nice pile of burnt residue. When I meter from one lug to the pile black stuff, I have continuity! Thus the short, as you warned me. Now, I removed a socket from a donor non-Philco chassis. It's the type that has "80" imprinted on the top, three wafers with a rivet in the center. Having never encountered this issue before, I'm inclined to use this socket. Comments?
#2

Probably OK, but I'd rather get good quality new porcelain socket that would fit the existing cutout. Measure and post a WTB in classifieds. Someone may just contribute to you for postage only.
#3

You're probably right, but I made the swap. Seems fine. Thanks.
