  • $3,000$3,200

The Retro Instruments OP-6 is an all-tube single channel portable mic preamp, heavily inspired by the classic RCA preamp of the same model designation. With gain potential nearing +90dB, this preamp suits itself extremely well to low gain ribbon microphones.

Modern features were incorporated based on popular modifications to the original RCA units, include switchable phantom power, pad, and polarity reversal, front panel instrument input, switchable input impedance, rotary output fader, and switchable meter range.
