srafi, try using the following settings for the 17D2...
At 60 dB of gain (no jumpers) the output level should be fine.
No jumpers for capacitance.
Jumper on F/V when using input impedance for low output moving coil cartridges.
Start with 200 Ohms or 300 Ohms setting on input impedance dial. (Five to ten times the internal resistance of 38 Ohms.)
If the sound seems overly bright or harsh, try the 100 Ohms setting. If the sound seems somewhat dull, try the 400 Ohms setting.
