Here’s an interest pentode to consider for phono stages. It was used extensively in instrumentation up until 1980s. There are a few examples around and you can check the Brimar data sheet <\/a>to see what I’m taking about. <\/p>\n\n\n\n\n\n\n\n

I checked a quartet of the military spec CV5086 which they measured bang on 100%. Here are some curves and Spice model which I’m sure you will find useful. In triode, it does give a mu of about 20. <\/p>\n\n\n\n
