The Doric Transistorized Organ is a model of
combo organ produced in
Italy in the 1960s.
History
Doric organs were also sold under the brand name
Ekosonic and were marketed as being the "lightest on the market" at .
Much like early
Farfisa combo organs, Doric organs featured a
monophonic bass section and a polyphonic lead which emulated other instruments by using transistor

s 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.

Operation
Inside the Doric is a line of circuits labeled with the syllables of
solfege, each generating a given tone in a scale. At the far left is a single circuit for the bass notes which shares a circuit board with the solid-state vibrato mechanism. As with many organs of the same vintage, Doric organs often have problems with
