Is there a good online source, for free schematics of phono preamps? I'd
like to build my own stereo preamp for copying high-quality LPs. I get too
much background hum from the phono preamp section of my solid-state
receiver, and I'd like something a bit better. I have plenty of experience
and lots of parts, the preferred preamp tube would probably be 6SN7 or 12AX7
/ 12AZ7 / etc, as I have plenty of these.
Anyone know some good links?
Thanks in advance.

I built this one some years ago, and like it a lot:
