84b rebuild but only one station
#6

i had previously wire brushed the pin sockets and deoxited them but i've no way to test the tubes save for the heaters.they all get warm and glow is all i can say.yesterday i removed and ohmed out the antenna and oscillator coils.they looked fabulous and was tempted to polyurethane coat them but decided against it. they were dirty and no outward signs of corrosion cleaned them in alcohol and a final rinse of non residue contact cleaner.the fluke readings were slightly different than the 260 readings but nothing significant. the ground tab on the oscillator was flaky so i put in a bonding wire using a ring stud terminal under the screw. fired it up again but no change. for the helluvit it replaced the .0014 mica with a .001 silver mica and no change.very strange these tube radio's wire going to the cap on the 2nd detector makes it squeal if i squeezie it while the set is on. i guess i become a capacitor to ground! looking for a cheap portable radio fot testing
