Here is a low voltage version I found googleing.

Just curious, what's the purpose of adding such tube buffer in the signal chain?
I guess any CD player has low enough output impedance to drive most anything.
Hi,
Tube sound!!!
cheers!
I imagined soTube sound!!!
Ok, go ahead, it's your party.
Build the one suggested in post #2.
The one shown in post #6 is a mess.
For the #2 one, you can get the +/-30V or thereabouts (it's not that critical, higher is better) from your power amp ... which of course I guess is not a Tube one.
By the way, I have commercially sold such tube buffers , under the brand name "Valvulizer" (tm) for those who insist on having some orange glow in their amps ... but I consider them a scam (yes, my own too).

What should be changed in the schematics if the voltage is increased to +/-42V?
thank you!
I can answer that one: raise cathode resistors, R3 and R31 to 15K or 22K.
As I said earlier, the higher the voltage the better.
I used rails between +/-42V and +/-70V for what basically is the same circuit.
That tube (or most others) will be *really* happy with 160V (total) voltage or higher, so any step you take in that direction is fine.

I want to compile special unit quality tube buffer with 6n1p-EV or 6922 for my CD-player.What voltage are your Power Amp rails?

Yes, that much I know , but what will you use to listen to it?
Hi Cookj!Wavebourn'shttp://www.diyaudio.com/forums/tubes-valves/171047-variable-harmonizer.html is what you need
What is included of the varijable-harmonizer, please a little explain
Thanks

Enjoy to tube/valve sound!!
