High-End Tube preamp with ECC88

For me, this preamp for this schematic provides a good sound!

If you need 1Vrms output, I would suggest this tiny modification to your schematic to give you even less distortion. Yes, you can also use DC on the heater but the improvement will be marginal. It will also be much less sensitive to the choice of tube (type and manufacturer).

We already told you so many times the different things that are wrong with this schematic. If you are happy with the sound from this circuit, that is good for you. But fundamentally there are faults with the design that you have been pointed out to you and which you choose to ignore. That's your decision, but do not post it claiming that it is good. It isn't.

So tell me what is wrong with this preamp, and if you are able to give a better schematic for tube preamplifier or line-stage.
thank you!

Hi,
To be more precise in the way this tube pre-amp with ECC88 measurements were made with a device CLIO with the input signal of 1V amplitude sine wave of 1027Hz at the 2 harmonic is 0.38%, and 3 harmonic is only 0.032!!
Cheers!

You say this preamp is high end. Please define high end.

simple....it means high prices....expencive, thats all it says

means its only highend DIY if its very expencive

Of course you did. Have you looked at the title of this thread?
