Select a Lundahl transformer for a specific cartridge
This table takes into account, the primary and secondary wire resistance of the transformer, the damping resistor (if used), and provides the actual voltage to a phono amplifier with 47k impedance.
- Green box: The signal is in the ideal range.
- Empty box: The signal is too high or too low.
- Blue box: The signal is in the ideal range, at the high end
Damping is always done at the secondary side. Please note, damping also changes the load on the cartridge. For this, we provide five such tables, with damping from 'very soft' to 'very hard'.
For building the transformers in it's own box, PCBs EE50 and EE51 are used. PCBs EE20 and EE21 are used to build the transformers into existing amplifiers.
Very Soft damping - Soft damping - Medium damping - Hard damping - Very hard damping

In case your cartridge is not listed, we probably can add it. Please contact us if needed.
