[2][3] Much like early Farfisa combo organs, Doric organs featured a monophonic bass section and a polyphonic lead which emulated other instruments by using transistor oscillators and a frequency divider section.
The Doric never achieved the same fame as Farfisa and Vox organs, perhaps due to limited distribution and a lower price point.
Although the Doric organs sold in the United States operated on standard 120 V power, the cable connecting the unit to a wall was unique, and, as a result, many organs are sold without plugs and users are forced to either replace the jack with an IEC standard, fashion a plug from appliance cords, or buy expensive vintage cables.
The power supply that the jack connects to converts household current to 9 V DC.
Inside the Doric is a line of circuits labeled with the syllables of solfege, each generating a given tone in a scale.
