the best diy phono tube preamp schematics
Hi all,
I am about to build a phono pramp and wanted to have a few designs to look at for ideas. Anyone know of a high-end schematic or circuit description on the web that does not use the common receiving tubes such as 12ax7s etc.. I am looking for something that uses special quality tubes etc. |

the Musical Fidelity NuVista preamp uses 6CW4's -- a nuvistor tube which was
popular as a low noise front end for frequencies above 50MHz. . I used a nuvistor 50MHz converter for 6m ham radio receiving. It was very quiet.
