hi,i finally got back to this one.the caps in question appeared to be mica but after breaking them open wax/paper caps were inside-junk!
replaced those,a.m. reception improved but short wave still dead. i noticed no change in operation with 1st tubes' gridcap wire removed,tube tested good. i found the filament voltage feedwire broken at the socket. as these are low voltage filaments you can't see them lit or not,even in the dark! they barely get warm when they are powered up. fixed the wire and s/w came alive,also needed realigned as i had done that with a dead tube.
radio is a strong performer now and you just gotta love a moviedial,phil
pics here-about half way thru page 2
