[R-390] 26Z5W Failure

[Gene Dathe]

OK, Bob, I think I see the problem now...

One rectifier burns out at some time or another, the remaining tube 
half-waves at 60hz for a year or so, and when it finally goes, and the radio 
doesn't work at all, the guy that hasn't been doing the PM's on his radio 
says that both tubes have mysteriously failed at once!

Guess I better stick my head under the rack more often to see if I still got 
two lit...
