[TenTec] Non-Ten Tec PS Switching Methods

[Curt]

I power my 540 with an SEC switching power supply rather than using a Ten 
Tec 262M or 252M.  This after reading about pass transistor failure issues 
and retrofitting crowbar circuits it just seemed too much trouble and risk 
to try using these old supplies.

The only issue I'm wondering about is turning off the rig by turning off the 
supply.  Of course the rig slowly dies as the PS caps bleed off.  I guess 
maybe the Ten Tec supplies somehow avoid this when mated with a 540.  What 
are other folks doing if anything to connect up to a non-Ten Tec power 
supply.
