The RCA OP-6 has been the behind-the-scenes "Holy Grail" tube preamplifier for ribbon microphones for well over 60 years. Its almost endless headroom and gain are legendary, as is the extremely thick, rich tone imparted by its unique design. The OP-6 was used on some of the greatest recordings of the past, and many of these coveted units are still in use today. Unfortunately, these days originals are hard to find,very expensive, and mostly don't perform to the technical specification they once did.
The vintage unit's feature set is also somewhat limited when compared to modern standards. While the preamp sounds just amazing on ribbon mics -or any other microphone type for that matter - with each pairing an adjustment to the input transformer (inside the unit) is required to adapt it to the optimum impedance. Further, some mics require 48 volts, which wasn't an option on a vintage RCA OP-6, and it's often hard for a purist to mod an amazing vintage '50s preamp beyond its original design to accommodate modern convenience.
So what if you could have a new "vintage style" OP-6 in all its glory (and then some)? A unit that would adapt to several mic impedances (switchable via thefront panel using a custom-wound input transformer), offer 48v for the mics that need phantom power, as well as having Mic and Instrument inputs? Wait no more! All the tone of the original OP-6 and fine detail of this glorious tube mic-preamp have now been recreated by one of the foremost experts in tube design of our time, Phil Moore, bringing this vintage classic kicking and screaming into the 21st century. Welcome the Retro Instruments OP-6 Portable Microphone Amplifier.
The OP-6 retains the integrity of the original circuitry, size and performance of the RCA OP-6, while adding many new features that will prove invaluable in the modern studio.
