I believe the most significant result of this discussion thread has been the
development of possible failures on the logic board as well as the fixes.
Knowing to replace the battery and ICs in order or to check them in sequence
as well as solder points can lead many of us who would have no idea
otherwise to success in repairing the logic board with $10 or $20 worth of
parts and our own time or it may lead to someone doing the repair on a time
and material basis.
Although I sold my OMNI-VI+ last summer and bought a OMN-VII to avoid the
logic board scenario, I personally would like to see the OMNI-VI series live
on another twenty or thirty years as its still a great radio.

I have not had mine for years and years, either. In fact, I waited a
long time for one reason or another to get one of these. When they
first came out I went through quite a WOW factor experience! Kind of
leaves a bad taste in you mouth, doesn't it?

I think this is a VERY important point that people involved with this
issue need to understand. I doubt that the average ham realizes the
kind of abuse a service department can go through - especially if you
actually give a rat's *ss about your customers. This is not a "kinder,
gentler world" that we live in today.
The use of the term "academic" was not meant to minimize the
situation, but to put things into perspective. As the famous John von
Neumann quote goes: "There's no sense being exact about something if you
don't even know what you're talking about." (paraphrase?) IOW we
have to know what's wrong in order to formulate a *specific* plan of
attack. But it's good foresight to have some extra ammo no matter
what.
Many of us could kludge a daughter-board arrangement as a fix, but as
Geoff, N3OWJ pointed out, the costs of board development are
prohibitive - even to Ten-Tec.
