    Help! Does anyone know of a fairly simple transistor throttle circuit with a 4 or 5 amp capacity? I'm running an A-B-B-A lashup of S-Helper Service F7s. Under load they draw upwards to four amps, sometimes more. I can run them only a short distance on Dallee's Yardmaster throttle (2.5 amps) before they pop the breaker. I have experience building circuits but don't want to get into anything too involved.

    Alternately, I would spring for a commercial throttle, but those I've seen are priced way out of my league, $200 and up. And that's just for one throttle. I'm going to need several eventually.
