Re: [TenTec] Using Non-TT Supply

["Paul Kraemer" <elespe@lisco.com>]

If that is an issue then use the VS-35M model with front panel adjustable 
current limit that can be set from 1.5 amp up to max of the supply.  The 
voltage is also adjustable from front panel.
I haven't taken each apart but I wager  the only difference between the 
VS-35M and the RS-35M is the adjustments brought out to a knob
