The tubes are 6DJ8 but it can take any other tube of this family such as 6922.   The LCRTube has a three section loading bay to allow for user configurable input impedance to what ever resistor\/capacitor termination value you want.  This allows you to have different impedances to accommodate different cartridges eg MM, HOMC, LOMC or the same cartridge with different loading depending on the recording idiosyncrasies or even set it to mono if you like.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003eRIAA Equalization type: Passive LCR network\u003cbr class=\"wixui-rich-text__text\"\u003eGain: 40dB to 60db \u003cbr class=\"wixui-rich-text__text\"\u003eInput impedance: user configurable\u003cbr class=\"wixui-rich-text__text\"\u003eOutput impedance: 20 Ohm\u003cbr class=\"wixui-rich-text__text\"\u003eInput capacitance: user configurable\u003cbr class=\"wixui-rich-text__text\"\u003eFull scale output level: 7.4Vrms XXXXXXXXXXXX\u003cbr class=\"wixui-rich-text__text\"\u003eSignal-to-noise ratio: -73db A-weighted with1\/f noise dominating (ref. to 0.774Vrms output)\u003cbr class=\"wixui-rich-text__text\"\u003eDistortion: 0.15% THD @ 0.774Vrms 1khz output.
