Ray Ivers	Re: 4xEL34 cathode bias ZNFB - done before? Lion, The AC100 is a different circuit; fixed bias from a zener regulator, off the negative tail of the PS HV bridge. I think the AC 80/100 designation resulted from a combination of the actual (80 watts) and intended (100 watts) performance of the amp; it's definitely not a 100 watt output, or at least the one I worked on wasn't. Interesting amp, though. Good luck! Ray

Lion,

The AC100 is a different circuit; fixed bias from a zener regulator, off the negative tail of the PS HV bridge. I think the AC 80/100 designation resulted from a combination of the actual (80 watts) and intended (100 watts) performance of the amp; it's definitely not a 100 watt output, or at least the one I worked on wasn't.

Good luck!
