Has anyone posted a schematic for a fixed bias VVR or could someone post one?  You have one tubenit?

You just need to add a bias tracker to a basic VVR/VRM/...

Check http://www.el34world.com/Forum/index.php?topic=8424.msg75788;topicseen#msg75788 for a possible implementation.

You could also get one of KOC's power scaling setups too Conrad. The ones I got are his FB-1 I think......the simpler one.
