Thanks, Dick. The last post I had on personal files was back in May. OK. 
Here goes:

I've been given an inoperative regulated power supply (120 vac to 13.8 
dc) with a generic circuit schematic that doesn't seem to represent what 
is actually in the supply. The only identification marks on the unit are 
(a) the capital letters "ER" (stylized, the E consisting the three 
horizontal bars only, followed by the R, and both letters 
leaning/slanted to the right), and (b) the apparent model number PS-109. 
It states that it is rated at 13.8 volts (fixed), amperage at 30-32.

Googling various combinations gets nothing useful.

Does any one have any idea who made this thing?  Any leads will be 
appreciated.

73,
Max, K5OVW
