Title: Bare Bones Exciter: 6F6 as a Triode??? Post by: W9ZSL on July 18, 2014, 05:54:11 PM Yes, a 6Y6 as the amp in a basic MOPA would get me where I'm going but what if?
Suppose I use the 6AG7 as an oscillator and a 6F6 as a triode PA? I noticed that with 285 volts on both the screen and plate and -20 volts bias, the tube will put out around 4.8 watts. What if I tied the screen and plate together from a common supply? Title: Re: Bare Bones Exciter: 6F6 as a Triode???

Interestingly, the Super Pro receiver uses triode connected 6f6's as audio driver and push pull audio finals. Good Ip/Ep transfer characteristics, -low distortion.

I'll probably run that off a 180 volt regulated supply. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
