[Milsurplus] U-229 solder pins?

[W2HX]

I should have asked this in my last post... anyone know where I can get the
little tiny pins that solder onto wires that then push into the back of the
U-229 connector?

Brooke! Thanks a lot for the link to your page. One sentence caught my eye
in particular "the PRC-126 now fills the room..." Mine certainly did not! 

I discovered that the cable that connects the 454 with the U-229 has a
short! I bypassed the cable and connected directly to the 600 ohm input of
the transformer and voila! Beautiful audio.

Now back to see if Fair Radio has a spare (working) cable! Thanks for such
great reference info on your site.

Hi Eugene:

I have some maintenance info on my web page:
