Moving Coil Transformer<\/h1>\n

If you’re looking for a great MC SUT, check this one out from Lundahl: LL1943<\/a>.<\/p>\n

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<\/p>\n

Overview<\/h2>\n
    \n
  1. Step up transformer: 1+1:16+16<\/li>\n
  2. Set up configuration options (selectable via jumpers)\n
      \n
    1. 1:16<\/li>\n
    2. 1:32<\/li>\n<\/ol>\n<\/li>\n
    3. Float\/GND jumper for secondary connection<\/li>\n
    4. PCB surface finish: ENIG Gold<\/li>\n
    5. Connectors:\n
        \n
      1. Standard turrets \/ 2mm plugs<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

        Version 02<\/h2>\n

        Added flexibility on the PCB for balanced\/un-balanced cartridge connection. See here<\/a>.<\/p>\n

        Price<\/h2>\n

        I made a small batch so I’m selling them until they run out at \u00a315 each plus Paypal taxes and shipping fees (see below)<\/p>\n
