This meant making a 3u wide module capable of holding all three vintage accurate transformers, dual concentric switches , pushbuttons and same exact PCB cards. Exactly what the name says. No downsized knobs. No transformers left out. No ICs in place of discrete class A circuitry. Just what the faceplate says: a 1073 in a 500 series format.\u003cbr style=\"font-family: Arial, Helvetica, sans-serif; font-size: 10.6667px;\"\u003e\u003cbr style=\"font-family: Arial, Helvetica, sans-serif; font-size: 10.6667px;\"\u003eFeatures\u003cbr style=\"font-family: Arial, Helvetica, sans-serif; font-size: 10.6667px;\"\u003e\u003cul style=\"margin: 1em 0px; padding: 0px 0px 0px 40px; list-style-position: initial; list-style-image: initial; font-family: Arial, Helvetica, sans-serif; font-size: 10.6667px;\"\u003e\n\u003cli style=\"margin: 0px; padding: 0px;\"\u003e70dB Class A Microphone preamplifier, HI-LO selectable minimum input impedance, balanced and floating.
