918 Powerplant

The RMA Powerplant is a transformer coupled preamplifier circuit built around the public domain 918 discrete operational amplifier designed by Deane Jensen in the late 1970s. Due to bipolar power requirements, initial implementation will be limited to modular or mains powered form factors. Engineering of the necessary power conversion module to operate the circuit on a standard +9 volt supply is underway.
