Moving Coil Transformer

If you’re looking for a great MC SUT, check this one out from Lundahl: LL1943.

I always struggled with the lack of PCBs available to mount them so I ended up designing and fabricating my own ones. I added a set of jumpers to allow for all combinations to be available and configured as needed. No need to re-solder

Overview

1. Step up transformer: 1+1:16+16
2. Set up configuration options (selectable via jumpers)
   1. 1:16
   2. 1:32
3. Float/GND jumper for secondary connection
4. PCB surface finish: ENIG Gold
5. Connectors:
   1. Standard turrets / 2mm plugs

Version 02

Added flexibility on the PCB for balanced/un-balanced cartridge connection. See here.

Price

I made a small batch so I’m selling them until they run out at £15 each plus Paypal taxes and shipping fees (see below)
