Hi,
It looks as if the MC Merlo is a rebadged/tweaked Goldring Elite, here's the spec...
Sensitivity
0.5 mV +/- 1 dB @ 1 kHz
Load Resistance
100 Ω
Load Capacitance
100 - 500 pF
Internal Inductance
2 uH
Internal Resistance
8 Ω
so I'd start here...
or set the capacitance to 0pF as there will be some capacitance from your tonearm cable.
