    SP14 and PH16 Preamps Voltage Gain in dB ? Empty SP14 and PH16 Preamps Voltage Gain in dB ?

    Does anyone know what voltage gain in dB I should get from the VTA SP14 and PH16 preamps in their standard kit configurations?
    (without the addition of SUT's in the PH16 case)

    Buying a new cartridge so the info would be helpful.

    Thanks.

    Voltage gain of the ST-70 per ch. into an 8 ohm load is about 29dB. 31.2dB for the ST-120. This is considering 0.6V input sensitivity yields max. power output and output voltage measured at the speakers.

    Thanks Arledgsc, but i'm looking for the voltage gain of the VTA SP14 and PH16 preamps. I've noted your Dynaco specs for future reference though.
