I thought you had found some very similar ones at Mouser or one of the other
supply houses.  IIRC, Surplus Trader had a 25 piece minimum order, which
surprised me since they bothered to mention the single unit price.  All 709
got sold?!!!!  Crap!  I've got a whole passel of various adapters that I can
run some tests with.  He who snoozes,
loses.  In retrospect I should have bought 25 and sold the excess off on
Ebay.  Next time.

This is your fault, really.  If you hadn't designed the XTB's I would have
had to continue building the device when I first conceived it. Only once in
the last few months have I plugged something in that substantially hosed
X-10 reception for one single circuit.  That was an APC UPS, if anyone
cares, plugged into an outlet very close to the main breaker panel, running
without an X-10 filter.  I'd sure rather be able to open them up and snip
whatever component out that's causing the havoc because it's common to all
of them. Nice UPS's except for the X-10 issues.

Thanks again for being my mail memory

The hunt begins again for 5 or so reasonable priced 12VAC 500MA Class 2
power supplies.  They're out there somewhere, I'm sure.
