ITEM DESCRIPTION:

This HHB Classic 80 tube-based two-channel preamp is one of the more versatile preamps around. Originally priced around $1500 new, they have become cult classics and are becoming harder to find.   Key Features: All-tube gain stages; transformer input stage; three-position high- and low-pass filters; output attenuator; tube drive indicator; instrument input. 

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. 

Along the way, the signal passes through second-order (12 dB/octave) low-pass and high-pass filters. Each filter knob has three frequency settings in addition to off. For the high-pass filter, these frequencies are 50 Hz, 100 Hz and 150 Hz. Low-pass frequencies include 5 kHz, 10 kHz and 15 kHz.

Both channels offer switchable phantom power, while Channel 1 also offers a phase reverse switch. Presiding over all the knobs is a backlit VU meter that shows output level. Additional level indicators include a tube drive LED and second peak LED. The tube drive indicator begins to glow at 0 dB, growing progressively brighter up to +12 dB. The HHB’s peak indicator lights when a signal gets within 5 dB of clipping.

Around back, the Classic 80 offers unbalanced 1/4″ outputs as well as balanced XLR jacks. A switch on the back panel lets the user select between +4 dBu and +18 dBu at the XLR output and lifts the 1/4″ output from -10 dBu to +4 dBu.

Will be boxed up tight for safe transit during shipping.

Thanks for stopping by!
