Tube Preamp for Dynaco ST 70

SF: I just popped over to the tube forum @ Audio Asylum and Joe Curcio has a new board (upgrade) for the old Dynaco PAS preamps (a recent thread towards the top of the page). Don't know how much the board is, but this might be something to look into (often see "minty" PAS's on Ebay for well under $200)? You could use it stock and then do the mod later on. Again, if you want a vintage preamp that is.

Good suggestions, Dekay. I would also like to add the MFA Magus to the list. Also, the Counterpoint preamps. They are very good preamps w/ phono sections. The MFA can be had used, of course, for under $600, and sometimes the Counterpoints are seen for under $400. Even though both these companies are out of business, they have repair and upgrade support by the previous owners/distributors. Both of these brands were considered to be some of the best units made at their time, and even now they compete with some fairly high-end stuff. Particularly if you are going analog, these units have great phono sections and will get you a great preamp/phono section for about the price of a mediocre new SS phono section alone. And you won't get a tube phono section new for anywhere near their price. They are very good value for the money spent.

What do you think of the Sony Frontier 1? Will it work well with my tube amp? Thnk you for your responses
