Thanks Matej...that was in triode at 1KV...will it really do IKV in triode? I have read some russian forum and they only get 800v/120ma in triode.

I wanna see pentode SE max power at 1Kv and OPT impedance...anyone ?

If you use GK71 as Triode is not would be better use the real Triode GM70??

In some forum GK-71 is better than GM 70.
ÃÊ71 < ÃÊ < Àëôàâèò < Ëàìïû < Óñèëåíèå < ÁàçàÏðàêòèêè < AudioDB : Áàçà Çíàíèé Audio

Just use your google translator....

They easier to drive and also lower opt inpedance than GM70.

You might try looking here. Nice online calculator and perhaps the site creator has a model. It is included on the calculator list and loadlines can be modeled in either Pentode or Triode mode.

The original poster has 2 GK-71 tubes, Right?

Can somebody come up with a good solution for him to use the GK-71 tubes?

Asking him to switch to a pair of GM70 tubes is a nice suggestion, but not unless he wants to purchase 2 more tubes.
And I am often guilty myself in other threads of suggesting the original poster purchase something other than what he started with.

brudertuck,

Now I see.
You took an old 2015 thread, and tacked your request onto the bottom.

You might have got a quicker answer with a new thread.
The old thread never asked for a pentode spice model.
