HELP..COLLINS 30L-1
 

I hope that I can get some ideas of my problems with my
30L-1...It was out of use for awhile, and I brought it up very slowly,
and all lookes fine..worked for about a day, but now when I drive it
even lightly, and dip the final with the tune control and very light
loading, even with very minimal drive, it pops the primary fuse...DC
voltage appears fine, and there doesn't seem like a lot else that can
go wrong...Could it be the 811A-s, and would it be possible to try to
prove that by running only one 811a at a time??? I'll be watching the
thread for any and all suggestions........Thanks......Bob
