[R-390] OT: Looking for TS-352 or AN/URM-105 or 1000ohm/v tester

Well, Les ...

You have to look at the other side of it.  Modified to take readily 
available batteries, those meters would last practically forever -- and 
could be serviced indefinitely.

That would screw up the industrial half of the military-industrial complex, 
wreck our economy and end life as we know it.  A big chunk of Corporate 
American income comes from military and govt. purchases.  If the stuff that 
lasts forever were kept online forever (a) people would lose their jobs* and 
(b) stuff would never be surplussed out and we'd never get any $10-cost the 
gov't. $1000 goodies.**

BTW -- yours is the cheapo method and mixes battery types in series (which 
may be OK but runs against my grain.)  I spring for 3 of the 3-AA cell 
holders.  The old metal type fit in the hollows for the original unobtainium 
batteries -- not sure about the plastic ones.

* Disclaimer/qualifier # 1:  Modify to read "lose their jobs that were going 
to be outsourced to Cucamonga anyway, so who in heck knows .."
**  Disclaimer/qualifier #2:  Most of these were surplussed out before it 
became customary to shred the stuff.

Have any of those $600 hammers been surplussed out yet, or are they going to 
be buried?
