[Collins] Greetings!! (and a question)

Tue, 5 Mar 2002 10:42:32 -0600

HI all.  A note to the fact that some series of 51J-x have been prone to
power tx failures. 
a short from hv winding to others, found one with short from the rect fil
to a hv section. 
removed b+ lead from rect fil and used 1N4007 diodes under chassis. that
was a year ago, 
still working fb.
