            Set is dead. HOT is blown. It is marked J6920 with fairchild 
 logo. It has the large case like a TO3PL although with fairchild it appears 
 to be TO-264. (same case size as 2SA1302). From that it appears to be a 
 FJL6920 which is rated at 1700V 20A 200W.  Didn't get a chance to pull the 
 fly (was a short day today) but if it is arcing wouldn't show on a ring 
 test. CRT does not appear to have a HK short and B+ comes up without HOT 
 present. Any idea where I can get a low cost generic version of this 
 transistor (in the event of a non testable arc) or any known failure 
 scenerios?
