Another solution is to use a tuner after the radio. • Ten-Tec's Chebyshev output filter apparently exhibits some Xc. To compensate for this, a 50pF tuned input C-in is used. Normally, c. 200pF is used for C-in of a 10m g-g tuned input. I've never had a problem driving any amplifier with my TenTecs. Are you suggesting that TenTec designed the Titan 425 to work with only TenTec radios? (If they did they sure would be placing a limit on the sales of the amp.) • A tuner semi-fixes the problem. There are no perfect amplifiers.
