[Wswss] Re: Need scehmatics for power supplies

[John W Lee]

I have an Astron  RS-20M  schematic.  Donno what the difference
is between that and the RS-35 is, other than maybe the RS-35 has 
more pass transistors.  Or bigger pass transistors ? 

And I am looking for a schematic of the  TRIPP-LITE  PR-40
power supply!    The company will not furnish me one.   Mine is 
broke and I need to fix it.   

If anyone has a schematic, please advise.
