Question Recommend a schematic for a Moving Coil head amp?

Could anyone recommend a tube based Moving Coil head amp schematic for me to build? Preferably something simple based on the 6922 or similar.

Has anyone built such a beast? When I build a head amp do I put it between the player and the phono stage or do I hook it into the regular line amp stage?

I have a Rega 2 with a Sony XL-MC1 hooked to a modified PAS3 type preamp. There is just not enough gain to sound anything close to reasonable. Even when I swap out the 5751 tubes for 12AX7s there is not much of a change.

Thanks in advance, I have never been disappointed in the knowledge given here.

You might want to check out the first stage of Allen Wright's preamps.

If I were to use a 6922/E88CC family tube, I would definitely use a step-up transformer if the solid state bit of Allen's design scares you.

Try a pair of CineMag CMQEE-3440A Step up transformers:

There are others using these for low output MC's, just search the Vinyl Asylum. I just may give them a try myself.

Those do look pretty interesting. Definitely simplifies things, no power or anything. I could put them right in my Pas3 and run a set of separate inputs to them.

I will do a bit more searching on them and see what luck people have had with them.
