I have received several reply tat suggest using a regular 1/4 or 1/2 watt
pot and a "current amplifier" horiziontal output traqnsistor (NPN). That
triggered my memory, and I found such a circuit by W3BYM in Electric Radio,
Dec. 2000, that included some other recommened changes for the Ranger.
Think I am all set now. Thanks for all the suggestions.
