Why we can offer a 5-year warranty on
RAM 285 tubes
There is a meter on the front of the amplifier which can indicate the health of the tubes—
get a bad reading, get free tubes!
As with our more expensive amplifiers, Bob employs his unique twist on a DC restorer cir-
cuit which has two main benefits —lower distortion without dissonant side effects and extended
tube and amplifier life.
Our amplifiers simply do not run hot. Like their more expensive siblings, they are the cool-
est running tube type amplifiers ever, allowing you to actually touch the tops of the output tubes
and never be burned!
The internal temperature of our amplifiers is a bit warmer than the inside of your mouth
resulting in an extremely long lifespan.
Due to the unique design, all the components in the amplifier undergo much less stress
than in conventional designs.
And, due to the efficiency of the concept, you may expect our amplifiers to outlive any oth-
er brand, and our extended warranties underscore that fact.
We warrant the RAM 285 for a full five years; that’s the amplifier and the tubes! We love
the fact that our finest competitors warrant their tubes for three months. It’s all about economics. If
your tubes tend to fail, limit the warranty. A manufacturer has no option; they must. Since our
tubes last for years, it costs us nothing to be heroic.
Perhaps even more importantly, not only do the tubes no longer fail every two or three
years, they do not degrade sonically as all tubes must when boiling away in every one of our com-
petitors amplifiers — a truly remarkable accomplishment and typical for Bob Carver, Absolute
Sound Magazine Hall of Fame designer.
General Operation
Bob has intentionally made the Ram 285 extremely simple to operate. Volume (gain) is
determined by your preamplifier or DAC.
Tube biasing, using the top panel control, is optional and will be covered on page 10 of this
manual.
That’s all there is…except for connecting your sound source, loudspeakers and line cord.
