Premium MC Phono Step-Up (SUT) Kits

The Premium Kit is supplied with the new LL1931, LL1933 or LL1941 MC step-up transformers. (click on the model numbers to bring up the data sheet) These were developed as a higher performance alternative to the LL9226 and LL1678. They use the same amorphous cobalt core material, but are substantially larger. The coils are wound with Cardas “6 nines” high purity copper wire.
The design was optimized for low to medium output MC cartridges and the sonic performance with these cartridges is exceptional.
The LL1931 and LL1933 provides 18dB and 24 dB step-up capability that is switch selectable, A higher step-up ratio version of the LL1931/1933, the LL1941, is also available for very low output cartridges or for use with low gain phono preamps, yielding 24dB and 30dB step-up.
For the Ultimate in MC Step-up the LL1931, LL1933, and LL1941 are all available wound with high purity silver wire as an option.
There is also grounding flexibility designed into the kit to allow the best performance with different types of tonearm cabling. 
Solder pads for resistors (1/4 or 1/2W) 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 kit includes connectors, transformers, PC board, wire, hardware, and enclosure. NOTE: the R-LOAD resistor is NOT supplied, as we do not know what cartridge is to be used with the kit!
The enclosures is a diecast aluminum case that provides exceptional RF shielding. The enclosure is physically small (4.57″ x 3.03″ x 1.48″, 16cm x 7.7cm x 3.8cm), so it can be located conveniently.
The standard color for the case is Cobalt Blue, but we can also offer the following colors, depending on availability. Please contact us first if you wish to have a color other than Cobalt blue, as it may not be available straight away.

Standard MC Phono Step-Up (SUT) Kits

The Standard Kit is supplied with the proven LL9226 or LL1678 MC step-up transformers. (click on the model numbers to bring up the data sheet) These are proven performers for the budget minded.
The LL1678 uses an amorphous core and the LL9226 uses a cobalt based uncut amorphous strip core.
The standard 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 LL9226 can give 14, 20 or 26dB of gain and the LL1678 can give 18, 24 or 30dB of gain, which is set using jumper links, which need to be soldered onto the SUT kit pcb, details of which are provided in the instructions which come with each kit.
Solder pads for resistors (1/4 or 1/2W) 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 kit includes connectors, transformers, PC board, wire, hardware, and enclosure. NOTE: the R-LOAD resistor is NOT supplied, as we do not know what cartridge is to be used with the kit!
The standard enclosure is a cobalt blue diecast aluminum case that provides exceptional RF shielding. The enclosure is physically small (4.57″ x 3.03″ x 1.48″, 16cm x 7.7cm x 3.8cm), so it can be located conveniently.
The standard color for the case is Cobalt Blue, but we can also offer the following colors, depending on availability. Please contact us first if you wish to have a color other than Cobalt blue, as it may not be available straight away.
