LINEAGE
The RM200MkI/MkII evolved from Music Reference’s classic RM9, the RM10, and the
state-of-the-art Music Reference RM9 Special Edition. The RM200MkI/MkII achieves a
news standard for musicality in stereo amplification. Using only a single matched pair of
KT88 of 6550 output tubes per channel, the RM200MkI/MkII easily achieves 100 watts per
channel.
Let’s take a few moments to learn what the RM200MkI/MkII achieves relative to a typical
100 watts per channel stereo tube amplifier in terms of

INSTALLING THE TUBES AND SETTING-UP YOUR RM200MkI/MkII
Please remove the tube set from the accessory box found with your RM200MkI/MkII. Note
the “’V’ Number” marked on each tube. With your RM200MkI/MkII
turned-off
and
unplugged
, please insert each tube into its corresponding position/socket as marked on
your RM200MkI/MkII’s top plate.
Please note your RM200MkII has two 70-Amp rated “high in-rush” power switches for long
switch life. One power switch is marked “Master/Forming,” and the other is marked “Play.”
Please make sure both power switches are in the “off” position.
Select a location for your RM200MkI/MkII that provides at least 2-feet of free air space
above your RM200MkI/MkII to allow for adequate ventilation of your RM200MkI/MkII. DO
NOT place your RM200MkI/MkII directly on a carpeted surface.
CONNECTIONS
Plug your RM200MkI/MkII into a 3-prong wall socket. If any other units in your system have
ground pins, we recommend you “float” the grounds of all your other units with an adapter
or “cheater-plug.” However, we recommend that you always ground your RM200MkI/MkII.
We find that the lowest hum is achieved in most systems when
only
the power amplifier is
grounded, as your power amplifier is the least sensitive component, and has the largest
ground current. You may also wish to defeat polarized 2-prong plugs in your other
components t allow you to reverse the plugs for the lowest noise and best sound. You
should do this systematically with your power amplifier first, followed by your preamplifier,
