Ultralinear / Ultralinear+ Integrated and Z40 / Z40+ Integrated customers can add an internal phono stage to their amplifiers.

The design started with a section of David Berning’s TF-12 preamplifier, which was translated into a more compact form factor. We kept the original equalization filter circuit and selected ultra-low noise integrated circuits for the active gain stages.

This internal phono preamplifier can be used with moving magnet (MM) or moving coil (MC) cartridges. It consists of two active stages and an optional step-up transformer. The first stage is fixed gain and handles the RIAA curve, while the second stage has three selectable gain settings available.

For best performance with moving coil cartridges, we offer Lundahl amorphous core step-up transformers. These can be configured to give 20dB or 26dB of gain.

Gain settings, resistive loading and capacitive loading can all be adjusted via the menu on the front panel or by remote control from the comfort of your listening chair.

See the user guide for details on configuration and settings.

The amplifier needs to be sent in for new hardware and/or reprogramming. Turnaround time on this is typically 3-5 days, depending on the production queue.

Shipping costs both ways within the continental US are included at checkout. For customers outside the continental US, additional shipping charges beyond what appear in the shopping cart may apply, depending on your location.
