I came up with a schematic for 4 X EL84 tubes starting with the first schematic by Kevin.
Basically each power tube has its own grid leak and coupling cap pair. For individual adjustment. The other way I thought was one bias pot per pair but it would be much better if it works to have a dedicated bias pot for each tube.
