I owned an RM-9 mk I for 10+ years and had Roger replace the on/off button (most failed) add mk II chokes and move the fuse holders to the top plate. In many respects, I sadly regrets selling that amp. The El34 Seimen tubes in matched Quads from RAM Labs were remarkable and had a midrange magic that was fantastic on several pairs of Merlin speakers I had/have owned. I wish I would have kept amp.
Highly recommend output and V1 V2 tubes from Roger. They sounded the best and not be a little I may add.
