NEXT, get a Linear taper potentiometer, (like an old radio volume control ) (rat shak ,$3,00) Say, your system is 0 to 60 Ohms , get your linear taper (pot) within a range of 0 to 100 ohms at 5 watts..
Doc after driving 30 miles to the nearest Radio Shack
I asked for said potentimeter, only to br told they don't carry sucah a creature ... the best they had was a 1k @.25 watts. I told sure you do Doc said so, well that made them look it up in their catalog athen they told me they don't carry anything even close. Any ideas where to find a 0-100 ohm @5watt pot?
I did find one close from an electronic store on the internet:
