Tube preamp with ecc88 (schematic-2)

Hi all!
Can this tube preamp to include of input tube buffer (Figure 1) or earlier should do some changes to the proposed schematic-2?
Thanks for the help!

*sighs* This last schematic doesn't work.

Congratulations, you're back in the endless loop.

Congratulations, you're back in the endless loop.

Hi Sy!
You are much more stringent in evaluating?!
cheers!

Tube buufer excellend!

Hi all!
These days, something I did, and here's the effort ....
What I got beauty, that kind of tube-Sound (high-ended)!
See photos,...Plis comment,...
Cheers m-r Ben (00940)

Cheers everyone!

 

[SY]

I'm delighted that you took the plunge and built something and even more delighted that you got it to work.

Well done!

Sy, will be true HIGH-END tube preamplifier with 12XA7 (ECC83) - Philips mini watt or,.... presented here!
Cheers!

High-End tube preamp

Hi all!
Here these days I ended up with a tube preamp that looks like this:
cheers!

I like how hole shrinkers were used as decorative fins.

Hi guys!
I want to create the tube preamplifier or tube buffer under this schematic. If anyone has some schemes comments let go. Any help is welcomed.
Just please tell me what is wrong what's wrong with this tube buffer (preamplifier)?.
Thank you for your cooperation!

Useless crap. Output impedance >10 kOhm. Wrong tube for this kind of aplication. Don't bother

Re:Very good tube preamp!

This preamplifier is with tube 12ax7(ecc83)!
And that you know gives great sound!!
Do not stare will be the schematic, and then comment.
thank you!

Of course i know. I have used them like everyone here for years.
And no, they don't give 'great sound' because they just are ecc83.
They may do, in a proper designed circuit. And the one i saw is faulty.

It's not "faulty" if you're shooting for a preamp that's an effects box. That may not be your target, and it's certainly not mine, but it's Gost's.

I think,

Its great you made something and have it working. If you like the sound then that's it!

If you are looking for a circuit with 0.000001 % distortion then perhaps its not quite the thing. However the ECC83 has a nice "Tone" and many people prefer the sound to ECC88 etc.
I must admit I did not know quite what you were trying to do, you have surprised me well done!
What's the point of a high performance circuit if you don't like listening to it?

Regards

The idea is to get the real tube sound with THD(second harmonic) >0.02%!
Cheers!

that´s properties of all hi-mu triodes i guess

No, not at all, but you can certainly run them in such a way as to get high harmonic distortion. Run correctly (in the sense of trying to minimize distortion), high mu tubes like 12AX7/ECC83, 6AQ4, 7788, 6SF5, and D3a have stunningly low distortion. There are probably high mu tubes out that that don't (12BZ7 comes to mind), but most of the ones I've tested are quite clean.

Excellent tube preamp with 12AX7

Hi guys!

This is excellent tube preamp with 12AX7!
and with much real tube sound.
enjoy!

Schematic?

Hi all!
Does anyone is interested in a complete schematic for the tube preamplifier with 12ax7 (ecc83) for very good real audiophile tube sound?
cheers!
