Default ef861 - guitar preamp

Hi, I am working on the pentode chanel of a voxac15 heritage schematics
ef86, ecc83, 2xEL84
mine is>
ef85, 6n2p, 2x6p14p
I found an alternative pentode preamp schematics with ef85, but not content with the result.
Not a half of the highs and the compression:
Vox AC15 Heritage Handwired - YouTube
Is it possible to work out something with some of these
ef861 (got them today)
6j1p (russian 7 pin pentode)

Еspecially with ef861, dont know where to start from about the design.
Hard to find any audio schematics with it (I know it is not its designation)

no one tried ef861 for audio?
no one ever found something suitable to replace ef86?
is that the only audio (pre-stage) pentode in the universe?

EF861 is similar to E180F and 6688, which if you search you will see are well thought of and used for audio.
