Mods,

You guys should consider starting a 'Nostalgia' section or something so this type of info can be posted for reference. Its also nice to learn about how technologies came about too.

Default Scientific Audio Research MOS450 225WPC Power Amplifier - superb!

Up for sale is the spectacular "MOS 450", 225 watt per channel stereo power amplifier, handbuilt in Canada by Scientific Audio Research Labs (S.A.R. Labs)

You'll have to ask around the audiophile community about S.A.R. Labs because it will be unlikely you'll ever find an advertisement for them. Word of mouth is all that is required, and has been for nearly 30 years.

The incredible talent behind the design and creation of S.A.R. Labs is Walter Romanyshyn. Equally incredible is his modesty. Walter quietly employs his gift of building beautiful sounding amplifiers and lets his work speak for itself. Technicians and designers alike marvel at Walters knowledge, skill level and craftsmanship. As others have stated: "Walter may on rare occasion be equalled, but never beaten!".

Onto the amplifier:

The MOS 450 utilizes many selected components in its construction beginning with two custom designed EI-core power transformers per unit. Power supplies utilize multiple arrangements of low-ESR storage capacitors for exceptional musical dynamics and an extremely low noise floor.

In order to achieve excellent linearity, wide bandwidth and superior transient response, the amplifier employs 8 fully complementary ultra fast HEX MOSfets per output stage. The transistors are mounted on specially plated heat sinks that provide ample thermal dissapation and sustained safe operation at high power levels.

In addition to the use of selected components, the MOS 400 also incorporates many design innovations such as an advanced feedback system design and a unique biasing layout which completely eliminates the possibility of any crossover distortion.


Specifications:

Power Requirements 120VAC@60Hz
Continuous Power @1KHz 225-Watts@8-Ohms
Power Bandwidth 10Hz-20KHz +0.25dB
Total Harmonic Distortion 0.1%
Damping Factor Greater Than 500 @8-Ohms
Signal To Noise Ratio Greater Than -100dB Below 200-Watts RMS
Input Sensitivity 1VAC RMS For 200-Watts @8-Ohm
Input Impedance Unbalanced:100K Balanced: 80K
Balanced Inputs CMRR Greater Than 90dB
Input Polarity Non-Inverting At Unbalanced Inputs
Balanced Pins +2/-3 IEC-268
Input Connectors 2-RCAFemale/2-XLR Female
Output Connectors 4-5 Way Binding Posts
Indicators 2 Overload LED's

The MOS450 is a rare acheivement, combining the desirable sonics of tube amplification with the punch of a solid state amplifier.

If you desire a superb sounding amplifier from a small company who creates exceptional build quality and artisanship into each peice then look no further.

You'd pay a lot more than this for an amplifier that sounds this good. From the original owner, it is offered at $1000.

Please contact for further information.

Default ALTEC Valencia - SUPERB - A7 Componentry

For sale are a beautiful pair of Altec Valencias, model 846B. Fully functional and ready for use. These are the home component version of the A7 "Voice of the Theatre" loudspeaker.

From the original owner who purchased them new so long ago, they are in wonderful condition. They really took care of them. The original cover templates have been recovered with cloth. Of course, after nearly 35 years the original reticulated foam cover has expired.

Serial numbers one digit off consecutive #7713 & #7715

These are 8ohm systems.

The 416 woofer cones are perfect. Original 806 diaphragms. All drivers employ Alnico structures. Original crossovers > N800-8K

You'd be hard pressed to find as nice a pair as these.

Buyers will have to arrange for shipping and carriers, this includes finding out all estimates (i.e. shipping quotes). I'll transport these anywhere within the city to the carrier but will be responsible for drop-off only (not for crating, palletizing etc)

Cabinets weigh approx 100lbs each and measure 75cm tall, 67cm wide and 51cm deep

US$850 (CDN$1000)

Hey thanks fella... yes, these Valencias are in super nice shape. The first guy to see them had his jaw drop open, followed shortly by his wallet. Glad you are enjoying yours... they certainly are efficient enough for tube amplification.
