Unusual tube query

The 6C10 compactron has 3 triodes each with a 100 amplification factor. Is there a 3 triode compactron with a 20 amplification factor for each triode?

... Is there a 3 triode compactron with a 20 amplification factor for each triode?

Reading between the lines of your request, you want a compactron that is 3 sections of a 12AU7.

    Google "compactron" and the first result is a page with a list of various compactron types.

    12AU7 is often described as a "medium-mu tube"

    Skim the list for types that mention 3 medium-mu triodes.

    Check out Frank's to get a data sheet of each type you're considering.

    Comparing candidate tubes to a 12AU7 data sheet, it appears the 6AV11 has 3 triodes identical to 12AU7.
