As I recall, all of the tubes in this radio save for the audio output and rectifier tubes are those d**ned loctals.
You will have to not only clean the pins of each of those loctal tubes, but also clean each hole of every loctal socket. Carefully scrape each pin of every loctal tube with a knife until they are shiny. As for the sockets, a small brush intended to be used between the teeth works great in this application, along with the use of spray contact cleaner. Spray contact cleaner into each tube socket pin hole, one at a time, working the brush into the hole and moving it up and down several times.
Just remember this: Clean one tube and one socket at a time! Don't pull all of the tubes and then forget which one goes where!
Dirty loctal tube pin contacts can cause all sorts of strange problems in radios that use them.
