[R-390] Re: Topics to start (Y2K Addendum)

[W. Li]

Here is one approach to the Y2K Addendum:

Compile and organize by topic all the important areas
such as "RF gear train rebuilds", "sensitivity and
alignment" or "power supply" or "recap projects"...
then go to the ver 2.0 of the exisitng Y2K publication
and hotlink to each area in question (or insert a
footnote about where to go in the Addendum). 

One underlying fact re maintenance procedures: they
almost always break down to mechanical AND electrical.
We could divide up each subject area into these basic
components for clarity.  We are often drawn to
electrical because of our training and orientation;
but we often neglect mechanical aspects as they are
obvious to us, maybe not so to a newbie.... 

OK here is my list on 'topics to start' (in order of
preference)

1) basic electrical safety measures  (not mentioned by
Joe Foley's excellent piece)
2) re-capping (when to, pro's & con's,
3) power supply (solid stating, B+ delay, in-rush
currents, fuses, AC power filters)
4) ballast tube subs (all schemes available)
5) PTO alignment
6) mechanical RF train clean and lube 
7) restoring front panels and knobs
8) panel meters
9) SSB options
10) tubes
11) mechanical filters
12) antennas
13) heat-buildup (IERC shields, fans etc)
14) weird and unusual problems with their solutions
15) test equipment
