Moving Coil Phono Step-Up Kit
The problem of getting enough gain to use a moving coil phono cartridge with a preamplifier designed for moving magnet cartridge use without lots of noise is easily solved using a Lundahl MC step-up transformer. These transformers are used by several high-end audio manufacturers for this same purpose. The Basic Kit was profiled and praised by Art Dudley in Stereophile magazine in 2007.
There are two levels of the Moving Coil Phono Step-Up Kit available, the Basic and Premium kits. These kits both provide two channels of transformer-based MC Step-Up for stereo reproduction. See http://www.kandkaudio.com/applications-guide/ for more applications information.

Basic MC Phono Step-Up Kit
The Basic Kit now employs the new Lundahl LL9226 for improved sound. This transformer is a rethinking of the already very good LL9206, incorporating what was learned in the development of the LL1931. It offers across-the-board better perfomance than its predecessor. The Basic unit can be set up for 14, 20 or 26 dB of gain when equipped with LL9226 transformers. Alternatively, the Basic kit can also be supplied with LL1678 transformers for 18, 24, or 30dB of gain, if you have a particularly low output MC cartridge or low gain phono preamplifier. The gain configuration is achieved by soldering jumpers on the PC board supplied with the kit. Sockets for resistors on the secondary side of each transformer are provided on the PC board so that the user can optimize resistive loading for the best sound.
The K&K Audio MC Phono Step-Up Kits are not really “newbie” kits, but can be constructed successfully by anyone with good mechanical skills and some soldering experience. Included with the kit is a step-by-step instruction manual. K&K Audio stands behind you as you build with telephone/e-mail support. However, if you feel that this kit is beyond your skills/inclination, we offer it assembled to your specifications, as well.
