Hi!

Could anyone tell me the 6P36S tube's (in triode mode) plate resistance?
Is the Ri ca. 680 Ohm or 1KOhm?
Has anyone any useful info about this tube in triode mode? Triode curves, load lines, etc?

Greets:
Tyimo

Thanks, but I know this one. It is from the Bartola Valves site.
I still don't know what is the plate resistance? 1K or 680R? Somewhere I saw the 680 Ohm value too.

It’s clearly stated on the chart, Ra ~ 1k.

You can see that with the analogue curve tracer the Ra is estimated. The other value comes from the spice mode which is more accurate. As you know the Ra will vary at different points in the curve.

You could use them as the pass element in a tube based regulator.
