None. I know what pico fuses look like. There is nothing anywhere
on these boards that resembles a fuse. I would expect one, too.
There isn't one.

I can't find anything that closely resembles that. There is a largish
3K ceramic resistor next to the 470uF caps... it's good in all three
PSUs.

On the back side, in copper, mine says...

JOULE POWER inc
107-001-027

and elsewhere it says, in copper

LCT60

and in ink

LCT60-1202

and on the top, in ink

802256101 rev c1

Good news is I found *another one*. This one (TK50) might have a working
supply. Have to check it out later.
