Any spice models around for AA5-esque battery tubes?

You know... little directly heated guys: 1T4/DF91, 1U5/DAF92, 3V4, 3S5, etc. I had a few in pentode and triode mode traced out in Curve Captor, but my hard drive crashed and I lost them... and i have not reinstalled Curve Captor or any of the Tcl support... or even my full operating system.

if anyone has some, I'd greatly appreiciate it.

I can't help with Spice.

The tube complement I can help with. 1R5 pentagrid converter as combined 1st detector/local oscillator. 1T4 remote cutoff pentode as IF amp. 1S5 diode/pentode as 2nd detector/AGC rectifier and AF voltage gain. 3S4 as audio O/P.

67.5 V. B+ is enough. You'd want 90 V. B+ for a 3V4 "final".

If you can scrounge up a 3 section tuning cap., a 1U4 TRF gain block will IMPROVE image rejection.

Thanx. I am trying to spice a few things to improve my understanding and to experiment... for example, I still can't get simple AVC like you see in these old radios to work right unless i dupe a previous circuit. i also have piles of those little directly heated pentodes around and want to experiment with them a bit, but would rather spice the whole thing first.
