Hi Gary
What Chuck said, PLUS:
Check and clean the tube socket contacts. You may have to carefully tighten the metal "fingers" that contact the individual tube pins on each with a pair of needle-nose pliers.
I just finished working on a Model 50 yesterday. Upon initial power-up it had the classic symptoms of a bad 1st RF coil - very poor reception unless you put your finger on the 1st RF tube grid cap. Pulled the coil and it was good! Then I noticed that wiggling the tube made the set try to work correctly. Cleaned and tightened the tube socket contacts and VOILA, proper reception.
On your set, I would suspect the oscillator circuit first, chiefly the oscillator coil.
