PC or EC92 tube model needed

[gorgon53]

Hi guys,
I need a good model for a triode suitable for a cathode follower that can swing some 300V pk to pk.
One candidate i have in mind is the PC92 because of the 250V heater to cathode rating.
Does any of you have a model that would work in Circuit Maker (3f4) or could easily get adapted to.
Other suitable suggestions/models are welcome
Thanks,
Pete

You might search for a 12AT7/ECC81 model, as this tube actually contains two 6AB4/EC92 triodes.

Best regards!

PC92 is a different heater spec for EC92, which is half an ECC81. Vhk (heater cathode max rating) is 100Vdc.

Ok, good to know that the ECC81 is, except for heater/cathode, identical. ECC81 model is easy to find.
Tnx Kay

Hester cathode of EC92 is 100Vdc too.

Yes, thank you Hector, for this reason i never intended to use this tube, i mentioned EC92 only because i thought the model for it would be OTHERWISE indentical and easier to find than a model for the PC92 (250V h-k)

PC92 also 100Vdc, or is this some special rating? I always thought it was the DC component (quiescent state) that dictated the Vhk rating.

It is cathode positiv to heater 100 Vdc and 250V pk, but negativ 250V dc and pk, so should be safe and more than enough for a 300V pk to pk output
