Very interesting. The one that catches my eye is the compensated single VR tube; stable Z and phase over wide frequency spectrum. Food for thought.

cheers,

That's what I use on the phono amp - 2-off OD3 in series. I haven't tested the compensation across them, I got approx. values from Gary Pimm, and it's around 0.1uF and 390R .
