I had an old Roland once, B size. B size printers made it obsolete.

It's amazing, thinking back, how labor-intensive electronic design used to be.

Which part order number was that?
Thanks,

Why not just put a voltage source in series with the wire to one of the gates? (or what Win suggested)
If you hard-parallel mosfets and run them in linear mode, it's probable that one of them might decide to dissipate 90% of the power.
And selecting/matching fets is NOT fun.
It's easy: one source resistor and one opamp per fet. Force each fet's current.

Or pick different fets.

I meant for simulation. Ah, maybe you did too. That would work but could he tedious to adjust.
Yes, I meant for simulation.
Without huge source resistors dropping volts, or closed-loop active balancing, paralleling mosfets in linear circuits is bad news.

for that .ako (A Kind Of) is neat, with that you can make a new component as a copy of another with just some parameters changed
