ypsilon mcStep Up Transformers
|
DESCRIPTION
The MC series moving coil step-up transformers are used to amplify the low-level output signal from a moving coil cartridge, bringing it to the appropriate level to drive a moving magnet phono pre-amplifier.
When terminated in 47k which is the standard input impedance of MM phono preamps the equivalent input impedance of each one would be:
The MC series transformers are large size single C-core double coil transformers using a proprietary amorphous core material. Special winding techniques were developed in order to minimize inter-winding capacitances and maintain a wide frequency response. They are optimised sonically to be as invisible as possible.
The transformers are shielded with mu-metal and are potted in 10mm thick soft iron nickel coated enclosures providing immunity from outside magnetic fields and a quiet and noise-free performance. The MC transformers have been developed in conjunction with the VPS-100 phono pre-amplifier but can be used with most other phono preamplifiers and with most of the moving coil cartridges available in the market. For optimum performance the MC transformers can be used within a specific range of cartridge output levels.
- The MC5 provides 5 times transformation ratio or 14db of gain
- The MC10 provides 10 times transformation ratio or 20db of gain.
- The MC16 provides 16 times transformation ratio or 24db of gain.
- The MC20 provides 20 times transformation ratio or 26db of gain.
When terminated in 47k which is the standard input impedance of MM phono preamps the equivalent input impedance of each one would be:
- MC5 – 2 kOhm
- MC10 – 500 Ohm
- MC16 – 200 Ohm
- MC20 – 140 Ohm

- MC5 may be used with cartridges from 0.8-1.2mV
- MC10 may be used with cartridges from 0.4-0.6mV
- MC16 may be used with cartridges from 0.3-0.4mV
- MC20 may be used with cartridges from 0.2-0.3mV
REVIEWS
Dagogo, Fred Crowder, 2011
"The Ypsilon VPS-100 is far superior to any other phonostage, tube or solid-state, which I have auditioned by a rather significant margin.... I hope that my enthusiasm comes through. In the end, I bought the review sample."
