6H30P preamp schematics

[Mrpong]

็Hi

I'm looking for some 6H30 preamp schematics by doing search on Google.

Here is what I found:-

Has anyone tried it? How good is it? Are there other interesting 6H30-based preamp schematics?

Thanks!

Check also the 6H6 Thread which is a very similar tube. There are a few schematics in that thread.

It would be 6N6P in the latin alphabet.

try google search for black art audio

I,m using 6H30pi into 600ohm output trannys I find it balanced and forget its between source & amps .

output stage.

power supply.

Gentlemen;
it is called 6N30Pi

I think both ways of writing (kyrillic and latin) are applicable worldwide nowadays...no correction needed.


EDIT: @mrpong: you may want to include the aikido schematic which CAN be built as lineamplifier with 6H30...lots of threads in here.

No, it is misleading. You can't write Cyrillic Pi using Latin letters, probably 6H30II will look similar, but not exactly.
Cyrillic letter looking like H means X, i.e. double diode. 6N30P is a double triode.

And yes, you may find lot of schematics in the Net, but 6N30P is a tube for computer usage, so it's linearity and repetitiveness of parameters is not good for audio applications if to compare to other tubes, though it is popular and overpriced. The same can be said about 6S33S (looks like 6C33C) that was developed for power supplies, without a linearity in mind.

Sorry for a bitter truth, but this information I believe can save money and time...

Very nice! The 600 ohm trannys are what on the other side? What's the ratio? Are you doing a push-pull?

behind the valve,s are
Line OutPut Transformers made by BlackArt in Australia
Model 6K600:20.6

the output trans are made for the 6H30pi .

Its BlackArts circuit so I would have to get premisssion to post it.

AIKIDO with 6H30P - I found one here. Do you refer to this schematic?

you could build an aikido. I think John Broskie has a table of values to uses when using different types of tubes somewhere in his site.

Is Black Arts still active? I emailed the person and no reply. The phone won't answer either. And the website looks like it hasn't been updated for years.
