CineMag Sky 10 Cinemag Step Up Transformer (10/5)

About the CineMag Sky 10 Cinemag Step Up Transformer (10/5)

The Bob’s Devices CineMag SKY 10 is a passive stereo moving-coil step-up transformer designed to increase the voltage from a low-output MC phono cartridge so it can be used with a conventional MM phono input, typically having a 47 kOhm input impedance. The unit uses CineMag SKY transformers with proprietary 80% nickel mu-metal laminations optimized for very low signal levels. It is housed in a hand-polished, black powder-coated cast-aluminum enclosure and includes gold-plated RCA connectors, silver-contact C&K toggle switches, and a ground/lift switch. The specified 10/5 version is the switchable model offering 1:10 and 1:5 turns ratios. Current Bob’s Devices listings show the SKY family and a heavier SKY 10-S successor/current variant, while the original product is often identified by retailers as the CineMag SKY 10; therefore, the exact manufacturing status of the original non-S model is not clearly documented.
