Tandy/Radio Shack Power Supplies - available

[ldkraemer]

Several years ago I purchased four of these Power Supply's in cardboard boxes. I've attached Photo's
of the Power Supplies because I have no clue as to what they are for. If anyone wants these Power
Supplies, or knows what they were produced for, they are available for the cost of shipping.

They don't look like any Tandy Power Supplies I have ever seen, especially when Astec made all the PSU for them, and the one shown is definitely made with Japanese markings on them, which I never have seen on any Tandy PSU before.
Radio shack might at one point sell them (not between 80-90 as I have never seen them in our store. you would have to look /test for power out voltages to see what it may serve as a purpose. Hope you find what they are for I be curious to see if anyone recognizes these...

Patrick,
These Power Supply's were purchased at the Dayton Hamfest back in the 70's or early 80's.
I also bought a lot of the Tandy 65 Watt and Astec Power supplies that were pulls from the
Model3's. There used to be a couple tables outside that sold items every year.
