I auditioned Ozzy62's system several years ago. He used an RM9 with a K&K TVC, the sound was phenomenal! I'm a former owner of the MK2..terrific sounding amplifier...I wish I still owned one. These particular tube amplifiers have plenty of gain, making them passive friendly. You should at least try a TVC with it just for grins.If you like the pot..you'll love the TVC!
