RO OpATube II 2-Channel Preamp PUBLIC

Richter Original "OpATube II" 2-Channel Guitar Preamp

Same as the first version of the RO OpATube 2-Channel Preamp but with a different tube. Here, the tube is a 12AL8 triode + pentode, which also operates with a single +12VDC supply-voltage on the plates AND their common heater. And the tube section has a gain of +21 dBV instead of +20 dBV. Other specs are otherwise the same as in the first version. Controls Include: Input Level, Ch 1 enable switch, OA Gain, OA Tone (Bass, MId-Center, Treble), Fuzz 1 enable switch, Fuzz 1 symmetry switches, Fuzz 1 Depth, OA Level, Ch 2 enable switch, Fuzz 2 enable switch, Tube Level, and master Blend. And this version uses the same power-supply as the first version.
