Description
The Classic 80 is a stereo tube mic preamp that treats the signal to three passes through the glowing glass. The trip through the Classic 80 goes something like this: transformer-coupled input stage, EF86 pentode main gain stage, two 12AX7 triode stages for gain and trim, solid-state balanced output stage. A front panel instrument input bypasses the input transformer.The Classic 80 uses a stepped gain knob marked off at 20, 30, 40 and 50 dB of gain. This feeds a gain trim knob continuously variable between -12 dB and +12 dB; this knob has a center detent for unity gain. A large output level knob attenuates the signal before the output, with maximum output at the full clockwise position.
