Default Looking for a schematic for phono stage.

I currently have a nice DIY tube preamp but it does not have a phono stage. Are there any schematics for a M/M stage to add to an existing preamp?

If you are looking for simplicity but good sound I would recommend the simplicidtic phono stage by salas.
You can also go for something more complex but very likely much better sounding then go for Paradise.

Hope this helps!

Here's a popular tube based design by Salas:
Valve Itch phono

And another by koifarm: Mini-Me phono preamp

My latest: The "Muscovite" 6S3P Tube Phonostage

Bassadventures, do look fore tube or solid state phono pre?

When you already have a tube pre may be a phono pre with tubes becomes to much harmonics.

Im actually looking to add a M/M phono input to add to the circuitry of my tube preamp. Right now it is just line in. Id like to add inputs for phono to the case.

What about this CNC MM Phonostage based on National Semiconductors design,one of the best.I am using one since two years.

Are tube phono preamps have a special sound compared to solid state ones ?
So far i've built Salas simplistic, Eliott P06, CNC MM Phonostage based on National Semiconductors design.
How it sounda tube based one compared to the my solid sate builds ?

I was planning to go for something more advanced like a Pearl 1 or Mini Me tube preamp.

Some experienced opinions would be apreciated.

Thanks!

Hi Atupi,
I remember you CNC now has an improved layout with double sided PCB,uncut ground plane on top,and different pads to accommodate different size of caps.I am now using it with LME49990 with +/-10V and it sounds far better than earlier.My DIY Power supply voltage can be adjusted by 5k trimmers,so its good.Here is the latest pic:

If you can find a 20-28V DC supply inside your preamp (less than 20mA needed), than you can use the simple circuit below.

Cheers
