[TenTec] Astron Power Supplies

[Stuart Rohre]

There are some scientific equipment applications for the Astron that require 
floating negative power supplies.  It also allows you to control where you 
establish your earth ground, in not having a sneak ground back thru the AC 
chassis ground of the power cord.  If you don't care to mix your DC and AC 
grounds, you can ground the negative to its chassis and live with the ground 
loop thus created.
