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

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.
- Cartridge output is based on 5cm/s, if your cartridge differs you will need to scale the value.
