MM Phono stage (kit?) for tube newbie

Hello all,

I've recently purchased my first tube amp - it's integrated but without a phono stage. I really intend to get into tube DIY in the future, and thought a nice place to start would be a phono stage for my new amp.

I could stretch to building my own, but feel it would probably be more sensible to get a (preferably cheap) kit as my first project, because I have no real-world building experience yet.

Any simple budget kit suggestions would be greatly appreciated.

Cheers!
 
I would certainly opt for a kit, and as complete a kit as you can find. Good phono stage design is extraordinarily difficult, and it's extraordinarily sensitive to layout, wiring, and grounding. It's the last thing I'd do from scratch or from a published schematic if I were just getting started.

Thorsten Loesch, formerly a regular contributor to this forum posted a relatively simple tube MM phono pre. Here's the circuit:

Here's the thread where Kofi Annan, DIY Audio's own comic relief, builds the phono pre:

People that have built it say it sounds very good, indeed.

Frank DeGrove also posted a line and phono stage in this thread, people say it sounds pretty good as well.

I'm seduced

Thanks for the links - I had also read good things about the Seduction, and I think I'll be going with that. I really think a kit's got to be the way to go for a first-timer like myself.

At that price, who can argue? All the other kits seem good, but are waaay out of my price range.
