Bryston TF-3 Moving Coil Step-Up Transformer

The Bryston TF-3 is a passive Moving Coil step-up transformer designed for vinyl listeners who want to use a low- or medium-output MC cartridge with an existing Moving Magnet phono stage.

Rather than adding another active amplification stage to the signal path, the TF-3 uses a completely passive transformer design to increase the extremely low-level signal coming from a Moving Coil cartridge before sending it to your MM phono preamplifier.

The result is the additional gain an MC cartridge needs while maintaining the clarity, low noise and simplicity that make transformer-based step-up devices so appealing in serious analog systems.

Turn an MM Phono Stage Into an MC-Capable System

Moving Coil cartridges typically produce significantly less output than Moving Magnet cartridges.

That creates a problem if you already own an MM phono stage you like but want to move to a higher-performance MC cartridge.

The TF-3 bridges that gap.

Connect your Moving Coil cartridge to the TF-3, then connect the TF-3 to your existing Moving Magnet phono input or MM phono preamplifier.

The TF-3 provides the additional gain needed before the signal reaches the MM phono stage.

Completely Passive Design

One of the most important things about the TF-3 is what isn't inside it.

There is no active amplification circuitry.

Instead, carefully designed transformers increase the cartridge signal passively.

For an analog signal measured in fractions of a millivolt, keeping unnecessary electronics out of the signal path can be extremely valuable.

The objective is simple: provide the gain required by a Moving Coil cartridge while adding virtually no additional distortion.

20dB or 26dB Gain

The Bryston TF-3 is available in two gain configurations:

• 20dB Gain
• 26dB Gain

The appropriate version depends on the output level and electrical characteristics of your Moving Coil cartridge.

This isn't a case where more gain is automatically better.

Properly matching the step-up transformer to the cartridge is important for getting the correct output level, loading and overall performance from the analog front end.

The Grid can help determine which TF-3 version is appropriate for your cartridge and phono stage.

Made for Serious Vinyl Systems

A step-up transformer can be an excellent solution when you already have a high-quality MM phono stage but want to move into a low-output Moving Coil cartridge.

Instead of replacing the entire phono stage, the TF-3 allows you to retain the MM phono circuitry you already like while adding the gain required by the new cartridge.

This also makes the TF-3 a natural companion to Bryston's own Moving Magnet phono solutions.

Simple RCA Connectivity

The TF-3 keeps connectivity straightforward:

• RCA input
• RCA output

The turntable connects to the TF-3 input, and the TF-3 output connects to the Moving Magnet input of your phono preamplifier.

There are no digital controls, power switches or complicated setup menus because the TF-3 requires no AC power to operate.

Do You Need a Step-Up Transformer?

If you're using a Moving Magnet cartridge, probably not.

If you're moving from MM to a low-output Moving Coil cartridge, that's where the TF-3 becomes interesting.

Instead of replacing a high-quality MM phono stage, the TF-3 allows you to add the necessary gain in front of it using a completely passive transformer.

The important part is getting the match right.

Cartridge output, internal impedance, transformer gain and the input characteristics of the MM phono stage all play a role in determining how the combination will perform.
