August 26, 2013 in The Aviator
Digging around the other day we came across a set of photographs of the very first Aviator, the “First of the Few”. This first unit was very much a prototype and although it had a full front panel initially it was mounted into a rack case with all the additional electronics circuitry bolted on. Later the unit was modified, put into a proper case and the additional circuitry tidied up. On the very early Aviators the 3 Voltage Controlled Oscillators and the Voltage Controlled Low Frequency Oscillator were built on individual circuit boards that were stacked. The 24dB Low Pass Filter, the Range Switch and Ring Modulator Circuitry were also on individual circuit boards.
When we did the update last year to build the “Last of the Few” we did quite a major redesign to tidy up the circuit boards without changing the actual circuitry or sound of the Aviator. The 3 VCOs and the VCLFO were all put on a new single PCB, the Range Switch circuitry was combined with the Range switches into a new PCB, and the Ring Modulator moved to the main front panel PCB. We kept the 24dB Filter circuit separate since it allowed the option to put different types of filters other than the standard SSM2044.
