Step Up Transformers

We are great believers that the best way to amplify the very delicate signals from a Moving Coil cartridge is to use a good quality transformer - this way you retain the dynamics and tonal colour of the original sound without unpleasant grain or distortion as found in many active MC stages. These units should be used between cartridge and a moving magnet phono stage, and provide gain of 10 times, so increasing the average MC cartridges output (approx 0.5mV) up to the average MM level (approx 5mV).

Pure Sound T10 mk2

The T10 is a compact and high performance step up transformer at a very reasonable price. It features adjustable cartridge loading switchable from 1:36 to1:18, therefore adjusting cartridge loading from 36 to 144 Ohms.

Pure Sound T10 mk2 step up transformer: £369.95

Silvercore ‘One to Ten’

The Silvercore range is hand made in Germany, the ‘One to Ten’ is excellent value for money, using high quality transformers wound with copper conductors and mounted in a beautifully polished stainless steel case. It’s sound has great dynamic prowess, majoring on weight and scale whilst the upper frequencies remain smooth and detailed. This is an excellent sounding transformer and something of a bargain at its price.

Silvercore ‘One to Ten’: £495.00

Ortofon ST-7

The ST-7 is a return to Ortofon making more affordable step up devices. Housed in a small but beautifully made metal enclosure, the ST-7 features sandwich wiring which is claimed to significantly improve the high frequency response and provide a very clear and open sound over the whole frequency range. High quality internal wiring is used to join the transformers to the gold plated socketry. Permalloy shielding is used to reduce the chance of hum pickup from surrounding pieces of electronics equipment and also help to prevent interaction between the two channels, improving stereo separation.


With gain of 24dB and suitable for cartridges with impedances spanning 2 Ω to 60 Ω, the ST-7 transformer is a perfect match for many cartridges, including the MC Quintet Series and the SPU Classic models.

Ortofon ST-7 step up transformer: £550.00

Audio Note Step up transformer range


The Audio Note range of transformers is very wide, with 7 basic models available which differ in terms of wiring and core materials from one another, each model is available with different impedances making a total of 22 models in all. The S8 and S9 are silver wired, the rest of the range are copper wired. All models are housed in a copper chassis and has a choice of brushed silver or black acrylic fascia.

Despite the large number of models, choosing the one that’s right for you needn’t be too difficult, we can advise as to the right gain and impedance required for your system.

The pricing of the models is as follows:

-Audio Note AN-S1: £POA at manufacturers request

-Audio Note AN-S2: £POA at manufacturers request

-Audio Note AN-S3: £POA at manufacturers request

-Audio Note AN-S4: £POA at manufacturers request

-Audio Note AN-S5: £POA at manufacturers request

-Audio Note AN-S8: £POA at manufacturers request

-Audio Note AN-S9: £POA at manufacturers request (pictured below)

Silvercore MC

The Silvercore MC is an all 99.99% pure silver wired step up transformer which uses amorphous toroidal cores for wide bandwidth. The case is made from a solid block of hard plastic that is milled to provide a well damped non resonant enclosure. The transformers can be made to individual requirements of between 1:10 and 1:30 ratio, with different loading impedances available, standard setups include the following versions, but please enquiry about any specials required:

Silvercore MC AG100 100 Ohm 1:10 ratio, recommended for up to 40 Ohm cartridges (suitable for most MC cartridges)

Silvercore MC AG25 25 Ohm 1:20 ratio for low impedance cartridges (up to 12 Ohm with lower output voltage)

Silvercore MC SPU intended for use with the Ortofon SPU cartridge series

Silvercore MC all models listed above: £995.00

Ortofon ST-80SE

The ST-80SE is the current top of the range transformer from Ortofon. The transformers are shielded by a permalloy case which is inserted into the aluminium cylinders that protrude out of the heavy (1.5kg)  box. This transformer is not adjustable and suited to cartridges with less than 10 ohm impedance, which includes the Ortofon Cadenza, Xpression and SPUs.

Ortofon ST-80SE step up transformer: £1,350.00

Silvercore MC Pro

The MC Pro is Silvercore’s flagship Step up transformer, made with the greatest attention to detail possible. It uses 99.99% pure silver wire custom drawn to their specification and large amorphous toroidal cores resulting in a primary winding with an incredibly low 0.1 Ohm DC resistance. The response of the transformers is extremely flat meaning there’s no need for loading resistors which will result in a very dynamic sound quality.

The transformer is available as fully balanced (with XLR connectors for use with balanced wired tonearms) or single ended with RCA (phono) sockets.

The case features stainless steel panels and is available with white Delrin, black acrylic or wood side pieces (Zebrano is the standard wood finish, but others are available to order, please enquire for pricing)

Silvercore MC Pro step up transformer with white Delrin or Black acrylic enclosure: £3,750.00

Silvercore MC Pro step up transformer with Zebrano wood enclosure; £3,995.00
