software for tube based stuff

[Rut]

Can anyone recommend schematic drawing software that incorporates tube
based circuits? Particularly transformers with multiple windings.

thanks

LTSpice. You can create absolutely everything you want. For transformers of
multiple windings: draw a few inductors, then couple them using the 'K' element.

There is a full suite of tube symbols and a mutitap transformer tube
output transformer (push pull centre 4/8/16 ohm) in SuperSpice. If this
is tube guitar amps your talking about, there are also single coil and
humbucker pickups, http://www.anasoft.co.uk/screenshot.html.

I downloaded the demo version but don't see transformers with a center
tapped secondary and another secondary winding for tube heaters. Am I
missing something?

Ahh... As I noted, I meant the centre tap primary with the 4/8/16 ohm
secondary *speaker* output transformer. I'll see about knocking up a PS
one with heater windings. I usually don't worry about the PS one, as one
usually just uses voltage sources. Simulation with heaters is rarely
done, so again I didn't bother to make one.

I downloaded the demo but I don't see transformers with a center
tapped secondary and another secondary for filaments. Am I missing
something?

You probably need to (1), build your own symbol or (2), make a
multi-winding transformer using the coupled-inductors approach.

Even building your own symbol will require a subcircuit with coupled
inductors.

I love to cook with wine. Sometimes I even put it in the food.

Rut,

Can anyone recommend schematic drawing software that incorporates
tube based circuits? Particularly transformers with multiple windings.

This link has models and step-by-step instructions for simulating
tube schematics with LTspice:

The OP was asking for schematic drawing software, rather than simulation
software per se...
