Ha, Jerry, hopefully you made it in time?
"I put my pants on one leg at a time...just like everyone else. The only difference is that once my pants are on, I make Gold records!" (SNL - Christopher Walken cowbell skit. I really wanted to post the youtube video but I couldn't find one that didn't suck or have extra stuff added.)
Remeasured R.F. (P-K) #78 tube just for the heck of it since I still had the coil hooked (but not re-soldered) in the chassis. Measured
1.8 volts.
Bypass of secondary coil I 'jumped' from R.F. plate to #12 cap and measured 270 volts on the I.F. and 270 volts on the R.F. (P-K) #78 tubes. [I've never done this before. Just had physics in high school and college. Never soldered anything, or used a multimeter so this is actually exciting as dumb as that sounds. I just walked past this radio in my parents basement for so many years-I'm 37 now--I realized if I didn't pick it the D**n thing up and take it home it would never work again!] Anyways, I can tell from that bypass and the schematic that the 'underwear' or Primary coil is open, and now understand what you mean. I'll still do the measurements you've outlined.
Ok, 'loop' to 'loop' are measuring .004 Ohms like you said Jerry.
'Red-Blk-Green' resistor tab is measuring .004 Ohms...so far so good.
The two tabs of the Primary or 'underwear' tabs (the Plate tab and the #12 Cap) are off the charts on Ohms, so you know what that means don't you?
It means that I need to go change my underwear.
