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

Purchase 2 x LL1941 and recieve a free project PCB. The LL1941 is a high turns ratio, high performance moving coil step-up transformer for turns rations of 1:16 and 1:32.
The transformer combines Lundahl's unique uncut amorphous colbalt core and their 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.
Wire
Available with copper or silver wire.
PCB
LL1941 comes with a free HASL PCB for your projects, or purchase a premium ENIG Gold PCB for an extra £20.
RCA Sockets
If you require RCA sockets for the PCB select yes, we will include high quality gold plated RCAs with your order for an extra £15.
Order
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
