My Ten Tec 238B L-Network tuner works well at 1500W. Some tuner networks, especially T-networks, can have very high currents through the shunt inductor. Bill, W6QR _ Topband Reflector Archives - http://www.contesting.com/_topband

My Ten Tec 238B L-Network tuner works well at 1500W. Some tuner networks, especially T-networks, can have very high currents through the shunt inductor. The largest issue with T tuners is capacitor value. Most tuners use generic 230-270 pF maximum capacitance caps, and that makes the
