Wanted: Vacuum Tube Phono Preamp for PAS

the full ranger · 5th March 2011, 06:13 PM

A friend, who is a novice builder, recently acquired an unmodified Dynaco PAS preamp. I have suggested an easy-to-build vacuum tube line stage that will run off a modified and updated PAS power supply but have not yet found an easy-to-build, good-sounding DIY MM phono stage that will also run off the PAS power supply. Any thoughts? Any schematics?

The Morgan Jones 'Valve amplifiers' book has an excellent bunch of info and circuits on this. I highly recommend reading it before moving ahead.

Thanks to everyone for their suggestions. I think the Curcio mod will be the easiest for my friend to implement so that is the one I will recommend.
