I don’t know (perhaps clio09 does?) if Roger left behind an assistant who can continue to provide service for the Music Reference products. But Tom Carione at Brooks Berdan Ltd. in Monrovia California knows the amps well (and appreciates their design sophistication and build quality), and can keep your MR gear working the rest of your life. Tom is a maintenance tech at an L.A. radio or TV station, and is in the shop on Wednesdays and Saturdays. He was Brooks’ electronics man for years, and stayed on after Brooks’ wife Sheila took over in Brooks’ (R.I.P.) absence.
It was Brooks who hipped me to Roger and his amps, of which he was a huge fan. He was happy to take more money from the customers of his who wanted to own bragging rights amps from VTL and Jadis, but those who were looking for value were directed to Music Reference.
BB Ltd., last time I was in the shop, had a healthy stock of RAM Tubes on hand, matched in pairs and quads by Roger himself. Best tubes in the business.
In my last email exchange with Roger (which I just reread, from only a month ago), I asked for his advice on installing a capacitor on the input jacks of the RM-10 Mk.2, to create a high pass filter at 80Hz for use with subs and the old Quad ESL, one of the two loudspeakers Roger used as his load in developing the amp (the other was the Vandersteen 1 or 2). Learning that I own a First Watt B4 active x/o, he advised me to instead x/o at 100Hz (the Quad has a nasty resonance in the 80-90Hz region), using Linkwitz/Riley 4th-order filters on both high and low pass. I offer that info for the benefit of other Quad/RM-10 owners, a magical combination.
In that email, Roger apologized for not responding more promptly, saying that he had been dealing with some health issues. Little did I know.
