Hi Artema

Because of changed circumstances/priorities, I can't build this model - sorry! Perhaps later...

Hello Artemka

I have now found a slot to fit my generic triode model to the 811A RCA data sheet.
But to finish/complete the model, some further information would be helpful, because the data sheet has no traces for negative Vg...
If you have a 811A sample available, would you please be so kind and measure
1) if possible the heaters resistance (when cold)
2) if possible also the heaters steady state current at 6.3V
3) if possible the anode current with grounded grid at Va= 50V and 100V

That would be perfect

Thanks in advance, Adrian

Hi Adrian!
thanks for your update. Actually, I don't have a 811a in my hands, but I am working on it . However, I will try ti check available online date, hopefully it is possible to get some data out of it.
BR Artem

Hi Artemka

There seems no further information available in the web about the 811A's behavior at neg. Vg.
So, I finished my model with a hint to the unknown accuracy for neg. Vg.

As my spice code is a bit larger than common triode model code, it would be an overkill to insert it in this forum. You will find my model on my website:

all the best, Adrian

Default 6P43p Triode mode at low current/voltage

Hello !

Would someone transform these low current curves to a Spice model ?
Thanks
Richard
