Klyne SK-2A Moving Coil Step-Up for Phono

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

General:
Beautifully made and very capable step-up device from Klyne.

This unique MC step up enables you to convert your favorite moving magnet phono stage, or one within a preamp or receiver, into a very high-quality low output moving coil cartridge phono stage.

It will also use the existing RIAA equalization from your MM phono preamplifier. This will sound much better than other "run-of-the mill" MC phono stage on the market.

This is one of the most musical, clean sounding, MC phono stages you will find.

Stan Klyne was famous for his low noise, higj quality preamps and phono stages, and this is no exception.

"The SK-2A is designed to provide the ultimate in accurate amplification of low level signals from low-output Moving Coil cartridges.

The proprietary non-inverting circuit built with premium quality parts results in an MC step-up amplifier with unprecedented clarity and naturalness of tonal balance. This unit is sonically transparent, vivid, and dynamic.

The SK-2A is equally compatible with both vacuum tube and solid-state preamps."

Technical Notes:
This device is *not a phono stage. It is an active MC step up device that is used to interface low output MC cartridges with conventional MM phono stages.

We do not have access to the manual for this specific version. We have set the DIP switches for an input impedance of 120 ohms. Experimentation with the contour controls is encouraged for best performance with your unique setup.

We have located and tested a suitable 18V power supply for this device but it is not the original part.

Packing:
Will be packed using our highly developed in-house process and custom packing materials.Specs:
Gain: 27.0 dB nominal. Channels matched to +/- 0.1dB.

Frequency Response: 0.8 Hz. – 350 KHz into 47K load (-3 dB points).

Noise: 90 dB below 5 mV. input. “A” weighted, 20 Hz. – 20 KHz.

Distortion: Total harmonic distortion less than 0.005% at 0.5V RMS output. Distortion decreases with signal and is extremely difficult to measure at signal levels in normal use.

Input Characteristics: Direct coupled with switch selectable impedance loads. 47K, 1K, 100, 80, 65, 50, 40, 30, 25, 20, 15 and 10 Ohms. 0-47K Ohms input impedance with user supplied resistors.

Output Characteristics: AC coupled with low distortion polystyrene and polycarbonate capacitors. Output impedance is 250 Ohms buffered.

High Frequency Contour: Switch selectable 6 dB per octave roll-off at 50, 35, 25, 20, 18, 16, 15, 14, 13, 12, 11, or 10 KHz. – can be defeated.

Power Supply: External AC to DC converter with built-in 24V regulator for 100V, 120V or 230V lines. Two additional internal regulation stages in cascade. The final stage uses a precision feedback regulator.

Grounding System: “Star” ground routing providing separate ground returns for input circuits, output circuits, high frequency contour, and amplifier power in each channel. This elaborate star supply and star ground geometry yields dual-mono performance with extremely low inter-channel cross-talk or input/output signal interference.

Finish: Blue baked enamel. Black anodized top plate. Tinted acrylic cover.

Size: Amp. 23.9L x 10.9W x 5.6H cm. Converter 8.6L x 6.4W x 6.1H cm.

Weight: Amp: 1.05 Kg. Converter: 0.7 Kg. Shipping: 3.2 Kg. (7.0 lb.)
