[Hammarlund] HX-50 snapping noise

[Robert Sauvan]

Hi all,
As many of you might remember, I have been working on my HX-50 
transmitter. It  all started with a major chirp. In the process I 
started recapping the rig. Each time I replaced a cap I turned on the 
rig to be sure all is well. It all worked great up until I got to the 
last multi-can cap setup.During this process I kept hearing a snapping 
noise occasionally. I occasionally heard the snapping noise before 
recapping as well but it wanst real bad, but I knew something was up.I 
couldnt actually pin point the snapping noise and pretty much was hoping 
it was one of the electrolytics. It was faint but there. So, I started 
replacing the last 3 caps one at a time. I was mounting them 
individually under the chassis and not replacing the multi-cap can 
because I couldnt find one. The first cap went fine. Was getting the 
usual output on the rig but I was still hearing the snapping noise. Went 
to the 2nd cap and then everything went to pot. I fired up the rig and 
keyed it liked I did on all previous testing but I noticed not quite the 
output as before and then the rig hummed and blew the fuse. Im sure I 
have everything hooked up correctly so Im thinking the transformer was 
what was making the snapping noise previously and now I blew it. Any 
ideas? Did I trash the thing? I hooked the old electrolytic back up but 
I think it was too late now since I think I trashed the thing. Any ideas?
