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

Purchase LL9206 and recieve a free project PCB. LL9206 is an input audio transformer for moving coil pickups. The transformer is built up from two coils, each coil with one secondary winding surrounded by two primary windings. This structure results in an excellent frequency response. All winding ends are available on the pins. Thus, the transformer can be used with a set of different turns ratios.
PCB
LL9206 comes with a free HASL PCB for your projects, or purchase a premium ENIG Gold PCB for an extra £20.
Order
Most transformers are made to order and incur a 3-5 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
