Desired load is below 40 Ω. Consider using a primary-side load for very low target impedances.

The LL1943 is a high turns ratio, premuim moving coil step-up transformer for turns rations of 1:16 and 1:32.
The Transformer combines a mu metal lamination core and dual coil structure with Cardas high purity copper wire in an oversized design. The objective is to provide the best possible MC transformer, cost no object.
Available with copper or silver wire.

Lead time
Most transformers are made to order and incur a 4-8 week winding time, we do stock some popular models in which case your order will be shipped immediately.

Instructions
- Select your transformer model and step-up ratio
- Enter your phono input impedance (default is 47kΩ)
- Enter the desired load impedance for your cartridge
- Optionally enter cartridge specs for gain predictions
- Click Calculate for loading recommendations
Notes:
When the desired load is below 40 Ω, you’ll see an advisory suggesting a primary-side load. Calculations still run normally.
"No resistor required" - Phono input already provides suitable load
