Well I made this today and it works very well. Adjustable power supply for my TS. It is very simple to make one of these things. The biggest investment is the power supply itself. I picked one up at Radio Shack for $39 bucks. The end connector is about $3.50 and you have a pass
thru that rocks at 2 amps with 3, 5, 6, 6.5, 7, 7.5v.
