Hi all, Call here is KB8ZZS.

about a 15 year hiatus from the hobby(renewed the license though), I
purchased an old Heath SB-100 the other day with all the manuals locally

I acquired a very clean 75A-1 at Dalton a few months ago. Serial # 1930. I
plan to pair it with my Viking II. I have re-capped it. It has very good
sensitivity and is even passable on SSB, although that is not its intended
use. I have been trying it out and find that if I tune up the band the
sensitivity drops but if I tune down the band the sensitivity is restored.
What could be the cause of this? Before I open the PTO can someone give
some advise? I thought it could be loose connection...

Im sure there are lots of reasons why we like working on "old stuff". To
reinforce at least one of the reasons, I found myself working on a modern
iMac wireless keyboard. For those of you not acquanted with working on
such a device, I present exhibit A:
