Hello

?

Has anyone ever built a model of a tube-equipped power amplifier in ?

There is one bugaboo about Spice modelling that

differed from some practical designs brought to us

through experiments, and that’s in figuring hysteresis.

?

Even though running numbers gave me starting points

to find pieces to fit, inevitably the finished product

was different than the paint-by-number sketch.

?

So the place to really find is to research historical

(hysterical) data and find various spread sheet

calculators, and see if they say the same basic

thing.

?

Right?

?

(I still ended up putting 30% of everything in

the junk drawer.)

I have […] also LT spice.? ?And both are a steep? learning curve.?

Oh yes, it's difficult.

I bought a large book in French, ISBN 978-2-10-076893-6. It helps me a lot, but... it's not easy.

?

In the examples I find, there's never a vacuum tube.
