Lundahl transformer step-up project for MM cartridge.

I recently upgraded my Raga Planar 3 with a Grado wood bodied Platinum reference cartridge. But output was low from the Pro-Ject SE phono preamp. LL1550 trannies supplied by K & K Audio and printed circuit boards allowed me to build a step-up kit in the wooden box the Grado cartridge came in. Compact and beautiful! For more information, see DIY Lundahl MM Phono Step-Up Transformers.
