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.
