I've placed some information about using moving-coil cartridges with the RedRoo preamp at: https://www.redrookits.com/phono-preamplifier/
You can download a pdf. It's pretty general so I'd be interested if some eagle-eyes can find some holes in it... thanks Phil

Lundahl transformers is one of the good ways of using moving coil cartridges. It all depends on the external
shielding, that is not clear to me how this unit is shielded. The tubes are not shielded which is a big minus.
Properly mounted lundahls can be used with moving coils to any riaa amp.

Thanks Peter, The case itself is steel and well shielded for both electric and magnetic components. Although the photo does not show tube shielding it is easily done. I might make that change but I haven't noticed any difference in noise levels/interference with or without so far.
