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.
