Bellari RP503 Microphone Preamp/Compressor/EQ Professional Tube-based Channel Strip.
This mic preamp features a simple-to-use compressor and a three-band equalizer with a sweepable mid-band. A tube gain stage follows the transformer-less solid-state mic preamp, after which the signal passes through an optical compressor before being fed to the EQ stage and output level control.
The preamp has been racked in my studio and is excellent condition. Note that all ICs have been upgraded with renowned Burr-Brown and Linear Technologies devices, and the original no-name vacuum tube upgraded with a vintage National 12AX7. This model of channel strip is a rare find!!
