'Downright Amazing!' - Art Dudley, Stereophile


Testimonials


"Without the slightest hint of brightness, the Bobs Devices Sky Cinemag SUT delivered detail with power, texture with touch... In all, the Sky Cinemag 30 is downright amazing for less than a quarter of the price of the reference to which I compared it (The Hommage T2)."
- Art Dudley, Stereophile (read the review)

Overview


Bobs Devices Sky Cinemag SUT
Ultra High quality laminations, lower inductance and superior sound. These transformers were especially designed and tested with several low-output moving coil cartridges. These are very difficult transformers to construct and require a precision manufacturing process that can only be done by David Geren at CineMag. The same construction techniques are used as in the 1131, except that the inductance of the SKY is even lower due to the lower step up ratios. In addition, the bandwidth is extended a little further.

Hand Crafted, Moving Coil (MC) Cartridge Step-up Transformer (SUT) built with new CineMag SKY (Blue Version) Transformers and gold plated hardware in a hand polished black powder coated cast-aluminum enclosure. All lettering is laser etched. Included are 2 switches: high/low gain and ground/lift.

Includes premium construction with C&K Brand Silver contact toggle switches, and Deluxe Gold Plated RCA jacks.

These specially designed transformers are wired to connect a moving coil cartridge (on a turntable) to a phono preamplifier, phono input of a receiver, or your preamp's phono input.


TWO MODELS - The SKY 30 and the SKY 20.

The SKY 30 is switchable for 1:15 (24 dB gain) or 1:30 (30 dB gain). The SKY 20 is switchable for 1:10 (20dB) or 1:20 (26dB)

See chart below.

CONSTRUCTION TECHNIQUES

All connections are Resistance soldered using the American Beauty system which avoids heat damage to the delicate insulation on the hair-like wires of the transformers. Test equipment is very low current to avoid saturating the transformer cores. You can count on a premier product that is state-of-the-art.

This unit includes a grounding post that can be used to connect your turntable ground and your preamplifier ground. It also includes a ground "lift" switch. In all modes, the transformer cases and faraday shield internal to the transformers are connected to the ground screw. In the "ground" mode, the phono system minus sides (negative sides) are connected to the grounding lug. This configuration works well for those systems where the turntable ground is connected to the negative leads coming from the phono cartridge or where the negative inputs to the preamp are internally connected to ground. In the "lift" mode, none of the conductors in the RCA jacks are connected to the case, ground, or shield and there is no electrical connection between channels. This design allows you much flexibility to mitigate for ground loops regardless of the configuration of your other equipment.

Bob takes pride in each and every set and provide customer support to make sure that they work well in your system.

Bob's Devices makes an properly constructed set of interconnects should you have trouble locating a set.

Moving Coil Step Up Transformers

Bob has personally built hundreds of step-ups and tested more than a dozen of the most popular step up transformers and several step up pre-amps used to match moving coil MC Cartridges to phono stage preamps. He takes the time to evaluate and incorporate suggestions and feedback from his customers. Each new design is personally scoped on a dual-trace Oscilloscope to ensure proper polarity, then sent a 0.5 mV signal @ 1 kHz to measure the ratio of the input and output voltage under conditions similar to how you would be using it. He listens to each and every unit to make sure it is sonically perfect. His current reference cartridges include: a ZU Denon 103R, an Accuphase AC-2, a Miyajima Shilabe, Koetsu Azule Platinum, Cardas Myrtlewood Benz Ruby 3 Silver, Ortofon Cadenza Black, and Koetsu Rosewood Signature.


Also available are Step up transformers with XLR connectors for those with balanced inputs and outputs, or mono units..
