No idea who the manufacturer is, huh?  I found a few pictures online 
with that model number, so I at least know what it looks like.  I'm 
headed back out to the China Sourcing Fair tomorrow (I'm in Hong Kong at 
the moment) and there are a few benchtop power supply manufacturers 
represented.  Actually, there are 4 pages of power supply manufacturers 
in the show guide, but a lot of them just do cell phone chargers and 
small devices.

Wait, I missed the addendum - make that 5 pages of manufacturers.  I 
don't know if my feet are going to survive another full lap of that 
place!  I'll keep an eye out, though.

I've learned you've got to be careful about model numbers - one radio 
manufacturer was showing an FT-1500 mobile.  Looks nothing like the 
Yaesu, though.  Interestingly, ALL of their models start with either FT- 
or IC-.  And another manufacturer has a TK-790, but it's a little HT and 
not easily confused with the Kenwood mobile.
