Phono - cartridge amp refit

I have post war radio/phono consoles that use crystal cartridges, which are troublesome compared to common ceramic replacements.

I have several of the latter in my parts, i.e. Varco CN65 and other mono carts not suitable for stereo records but fine for 10" LP and 78's using their .3 mil sapphire stylus.

Is there an old thread some where about building in a X10 gain pre-amp to use the ceramic cart? I plan to make one from a 6AV6, 6J5, 6SQ7 or other triode with only 0.3 amp heater rating (equal to two #47 pilot lamps).
