Now we're gettin' somewhere. Can you point me in the right direction for the meters? Every time I search eBay or Aliexpress there are a zillion DPMs with voltages all over the place. My eyes start to glaze over... Did you use a fixed resistor or a multi-turn pot? Wattage? Sorry about the noob questions but my eyes aren't open enough today to glaze over in the first place. I know the theory but I'm having a hard time with math at the moment. Terry Bowman, KA4HJH "The Mac Doctor" https://www.astarcloseup.com “...the book said something astonishing, a very big thought.
