I've used lots and lots of Lambda power supplies, mostly bench

never seen one die, so I can't speak to the "odd IC" problem, but as
a frequent user over the years, I have nothing but good things to say
about them.

Hi
The only problem I've had is their " long life " electrolytics.
I've had to replace several of these on their LED readout
supplies. These are used for the low voltage supplies
used for the IC's of the display.
Still, they are the most robust supplies I've worked with.

It has a
trangle with a lamda in it.
I've heard of Lambda brand PSUs, and I've heard they used 'odd' ICs
that
are now unobtainium. I could well believe a 723 with a difference
reference is the sortof trick they'd pull...
