Otherwise the schematic without power supply worked Harkonnen with some Crotian DiyAudio.hr!
P.S.
Small recommendation: stick to topics.

Yes, we need to know. At least she's much closer to the hi-end than the silly preamp.
Why is the power supply so complex? I would think that you could get rid of more than half of the parts shown and it would not make a difference in the overall performance.

Hi
If we want to create a quality preamp (High-End) should be for noise to make a good quality power supply, and that means the sum of power supply interference and to reduce to a minimum!
Semiconductor devices today are very inexpensive and very long lasting!
enjoy!

I would say that if we want to make a high quality preamo, or high quality anything, we should study how the devices that we are going to use (valves, diodes, transistors etc) actually work...
the preamp that is posted a while back is very quiet, no hum no hiss and sounds mucho fabololso...😉😀
Long lasting....? That would explain the 200V cap with 204 volts across it...? Or the 3.3V zener that gets killed by the switch on surge...? Never mind the unnecessary resistor R3, or the extra resistors used to bias the heater rail - two resistors are enough - there's no benefit in having four.
Too much BS for me. I'm out of here.

Hi 12E1!
I did not understand you?!, ... be a little specific, ...
Here's a new schematics for pre-amplifier.

It's not "his" schematic- he lifted it from someone else without permission.
I would suggest that the OP carefully define what he wants the preamp to do, in technical terms- gain, input and output impedances, the usual. Until then, I would suggest others not flail around trying to help someone try to choose or "improve" a design until he figures out what he actually wants.

I think he just wants to talk to us. He keeps putting up preamp designs, mostly either bad ones or copyright infringements, or demanding that we put up preamp designs. He seems to have no intention of actually building one, and doesn't appear to understand our comments.
Hi
Put a 10k resistor anode and cathode resistor 470omi (Vta), you will see how this preamp sounds nice. Changes to the semi now I am not able to insert.
Enjoy!
Best Regards

Hi Sy!
I want good tube/valve preamplifier or Line-Stage wath gain<8x and which will prevail steam harmonics.
The largest second harmonic to be <0.5% at the maximum output voltage!
The output impedance to be preamp Zout<1k!😎
E-look something like the graph.😱
thank you and cheers!

Come on guys let's move on,... your offer solutions schematics etc, for high-quality tube/valve pre-amplifiers.🙂
thanks!
thanks!
Build your schematic. Report back how it sounds and if you would like to make changes. That would be a good place to start.
This is a DIY site. Why don't you find a good design and show it to us (via linking rather than stealing), asking for our comments. Don't keep putting up poor designs and telling us they are wonderful, or demanding that we provide you with designs. This game is getting boring.Gost22 said:
