Hi, Tom:

I had that same problem with a 12 A Astron.  Friend tightened the 
laminations on the transformer.  Don't know how he did it as he took it home 
with him.

Since I wrote you last, have had 33 radiation treatments and 8 of 40 
Hyperveric Chamber treatments.  The latter is done in a plexiglas tube like 
CAT Scan.  Oxygen concentration is 100 percent and pressure is 2.5 times 
earth atmosphere at sea level.  The only sinsation is popping and pressure 
in ears when compressing and decompressing.  Have 80% or better chances for 
full recovery.
