MC/MM RIAA Phono Class A Pre-Amplifier
The New Holton Moving Coil and Moving Magnet RIAA pre-amplifier has been developed as a stand alone pre-amplifier with its own on board low noise DC power supply. It only requires the addition of a 15VA power transformer to power it.
Power the RIAA preamp from batteries is also possible.
It is also designed to work with the New Gain Block One preamp found else where on the Holton Audio web site.
The new RIAA preamp has dip switch selectable input impedance for moving coil and moving magnet cartridges as well as dip switch selectable gain setting for both types of cartridges.
The printed circuit board is made from high quailty 2mm thick FR4 material with a thick 2 ounce copper foil, Gold immersion plated.
Testimonial from Henri Cohen in France!
Hello Anthony sorry for the late response, for a few days I have been comparing different preanp phonos and I am very happy with your Phone Preamp, there is a nice stereo image, the medium and treble sound well detailed can be a little dry, I like! the bass is present and not muffled, it is clear, precise and well mastered. i use ortofon mc rondo blue with shibata diamond, well I am very happy with this achievement. Thank you so much to pleasure!
