High-End preamplifier with ECC82!

radio · 25th February 2011, 07:14 AM

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!

This is absolutely not "High-End"!

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....

Hello All !

I'd recommend a scheme (circuit) for the "High-End Preamplifier with ECC82" or ECC83

Thanks

It's kind of easier to recommend circuits without ECC82 or ECC83

Here is one, maybe not High-End but with ECC 82 as you wanted.

Pozdrav zemo

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?

When the price gets high.

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.
