And it was as you stated. I swapped one from my "extra" BA and it works
like a champ. thanks!
And, in the process I finally looked for the NPG jumpers and found out
which slots didn't have them (which made my ts-11 much happier :-)
I also "tuned" the 785 supply - it was lagging around 13v. I assume
cranking it up to 15 is the right thing to do.
Anyone have an RA81 HDA they don't need?
