On offer is an all original Music Reference RM-9 MkII stereo tube amplifier   Condition is rated as 8 for age.

This is THE Vacuum Tube Amp That You Are Looking For !!!!!

ATTENTION: This is the highly coveted MkII version -- not a converted MkI -- with the three-position selectable feedback/gain switch.  It also includes the IMPOSSIBLE to replace original tube cage !!

For the uninitiated, most consider the Music Reference RM-9 MkII to be Roger Modjeski’s finest work. A true Made in USA audio classic !! It was (and still is) without peer in the higher-powered tube amplifier arena. With selectable feedback/gain and the ability to use EL-34, KT-66, KT-77, KT-88, and 6550 tubes – basically anything octal – the ability to fine-tune the amp to your system and taste is wide open.

Impeccable Design: 

All vacuum-tube design with a10,000-hour tube-life. A driver balance-adjustment pot, and built-in bias adjustment pots with LED monitors for each channel. Hand-wound and –stacked silicon steel Output Transformers, potted under vacuum in silicone rubber for the ultimate in long life. Taps are provided for 2, 4, and 8 ohm nominal loads via copper terminals. A tertiary winding is used to provide negative feedback to the driver stage while improving stability into highly reactive loads. The amount of feedback and hence overall gain is selectable via a 3-position toggle switch. You may select 10, 14, or 19dB of feedback during listening so that you can fine-tune the amp/speaker interface. The available gain decreases with feedback from 36dB to 27dB. The switch designations of "LO," "HI," and "MED" refer to the amount of gain available.

Music Reference RM-9 MkII Stereo Power Amplifier Specifications:

The Mk.II upgrades include an increase in output power to 125Wpc, a new style wood frame which is more visually pleasing than the one used on the original RM-9, a robust rocker-style On/Off switch, and copper five-way binding posts. The output-tube fuses are top-mounted together with "Fuse-Out" indicators—a major convenience. The most significant upgrades are those in the power supply: Capacitor energy storage was increased by 50% over that of the original RM-9, and dual chokes were added to the power supply—a filter dedicated to each channel.

Dimensions: 17¾" W by 11¾" D by 6½" H. Unboxed amplifierweight: 60 lbs.

This Specific Amplifier:

Cosmetic condition of the top-plate, oak wood base, and transformers is excellent for this vintage piece of audio history. The amp is fitted with the standard RAM-branded 6DJ8 variant input & driver tubes, but has the distinction of running an upgraded and exceptionally matched octet of Gold Lion KT-77 tubes sourced from Kevin at Upscale Audio. The only cosmetic “nits” that I see with the amp are minor marks here and there which are to be expected from age. The top plate is the absolute cleanest one that I have ever seen for one of these.

What comes with this Amplifier Listing?

Excellent original condition stereo amplifier with tube cage, natural oak base, standard RAM input tubes, upgraded KT-77 output tubes, copy of Stereophile review article, and copy of special Collector’s Edition Version of Owner’s Manual.

The Fine Print:

• All sales final – NO EXCEPTIONS. 

• I am open to USA sales within the 48-contiguous states only – NO EXCEPTIONS.

• The amp is in exceptional condition for its age. This is, however, a vintage piece of audio equipment, so there are minor marks here and there owing both to age and to the original hand-crafted nature of the amp (Roger made only a little over 900 RM-9 amps total if you add together all the original and MkII versions).

• The amp is 100% functional prior to shipping and sounds exceptional.

• Buyer pays for shipping, shipping insurance, and delivery signature service as required by the carrier at this price point for declared value. An additional $20 charge will be added to the payment invoice to cover the insurance and signature confirmation costs since these are not included in the shipping cost quoted by the Audiogon shipping calculator. 

The Stereophile review said it best: “…I consider the RM-9 MkII an authentic American classic. Forget the McIntosh 275 or the Marantz 8B—they don't sound nearly as good. Despite its stereo configuration and modest size, the RM-9 is a genuine Class A contender.—Dick Olsher”

Questions for the seller
Hi does this amp have a phono line?
Hello, i am not certain that I understand the question as it is an amplifier only and not an integrated amp.
