Recently as discussions here related to some tube options I came to the conclusion that my memory of past tube rolling experience was fading. Even to the point of not recollecting having tried combinations, much less what my impressions were. I have no intention of starting over but I did try to put on paper the options so that I can reference them in the future. Also, as I plan to will my Inspire Amps and Preamps to my kids, they could use a little guidance. Anyway see the attached if interested. It may be comprehensive, it may not. Keep in mind my efforts were objective and manufacturer's were left out completely.
