Darrell, That amp you built with the 4-1000 was a "killer" in more ways than one! Time for a confession..

To run a linear amplifier at 375 watts of carrier and 100% modulation, you will need around 800 watts of plate dissipation. For a short time a number of years ago, I tried running an AF-68 and a 4-1000A linear amplifier. I could never get more than around 450 watts of carrier and stay linear............I didn't need a heater in the shack either. 73, Darrell, WA5VGO 73, Darrell, WA5VGO ______________________________________________________________ AMRadio mailing list Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] -- No virus found in this incoming message.
