[GreenKeys] 60 ma Loop Power Supply?

[Dave Hunter]

Hi Everyone:

I have my 28ASR running now, but it needs a loop power 
supply to stop the printer from chattering and to make it 
respond to the keyboard.

The keyboard problem was resolved by simple cleaning and 
lubrication, and the tape punch appears to be working now 
(but hasn't been checked with tape in it).

What I need now is a simple 60 ma. loop power supply to 
feed the selector magnets. Basically, for now, I need it 
only to supply the loop current  so I can get the printer 
to respond to the keyboard.

Does anyone have a cheap and simple way to do this?
