Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: Distortion

Seems like a plan; the 'bunching up' of the plate curves at low current( gm shrinkage ) is unavoidable. Driving the load line through the knee where they bunch up again is avoidable.

I put together a 6AV5 pentode linestage once. g2 at 75V, B+ about 250 and filtered the heck out of the B+. Ran a 510R load, idling at 50 mA. Nearly vertical as far as the tube was concerned. That load line went nowhere near the knee, and it sounded quite good( as well as letting me use a 0A3 to shunt reg the g2 supply ).
cheers,
Douglas
