Preamp 47K load. Cartridge needs 330 ohm

Experts!!!

Preamp is Conrad Johnson PV7.  Recently refurbished by Music Technology.

Cartridge is Miyabi Cello Chorale 0.35 mV and needs 330 ohm load.

How do I solve.  Preamp load not adjustable.  Any interface box like Puffin?

Or maybe a Andover SPINSTAGE PHONO PRE-AMP

Or a Lundahl or similar transformer?   I am not sure.

Thank you.
