Hello!
The measurements refer to the preamplifier is given below in Scheme (Figure 1)!
Please someone let that little comment about this preamplifier, if it does as a power preamplifieramplifier.
Feedback to be about the sound and display measurements if it worked.
If someone izradijo this pretpoačalo and made some measurements and some show here (frequency response and attitude towards the second and third harmonic!!?)
Many thanks in advance!

Why not ? For best implementation of that circuit , octal tubes such as 6SN7
could be used . Lower and upper tubes would need separate filament supply ,possibly DC regulated ,and the upper one needs also a reference to B+.
Major importance should be given to the power supply section ...which 'sounds' and can be detected as the 'line preamp' circuit .

Nah, Personally--I dont like it!
Be better to do a Proper Mu stage, maybe with mosfet on top or a Pentode....
Dont like the ECC82 either, Nasty little things IMO....

High End preamplifier with ECC82-Circuit!!
Hello All !🙂
I'd recommend a scheme (circuit) for the "High-End Preamplifier with ECC82" or ECC83🙄
Thanks

Why bother a tube preamp your source is also solid state.
Only use of tube pre-stage is for a turntable IMO, then from source there is no solid-state involved.
And in when stage the tube preamp design becomes high-end?

Why bother with tube amps at all if the source is not a a turntable?
ECC82's can sound good in a mu follower topology, I can post a schematic if you're interested.
Yes I am interested, and till now I do not understand what advantage your talking about.
And what is the mu follower topology concerning?
What if I have a LP that was recorded and mastered on SS equipment, should I not bother listening to it on my tube amplifier? 😀
Lets leave aside the silly topic about the source. I don't like this tube but I have some nice NOS 12AU7's so I built this preamp. It sounds quite good. Don't know the reasons why this tubet sounds good in mu follower and awful in a simple grounded cathode configuration (so don't ask me).
BTW, schematic was recommended by Bruce Rozentblitz. Probably misspelled.
EDIT - Mine has a different power supply.

I posted a Shunt Regulated PP in the link at #3 .
I also did it ...many years ago
Edit : also Radio shows a Srpp ....
