this auction"Well here is a bit of an odd item which i know best part of nothing about!
It looks to be a rather complicated home made 6 voice osc/tone generator. It is packed full of old switches and pots and a maze of wires inside. Built in the late 1970s looking at the date codes on the components. I was told the chap that built this use to bulid effects and units for tv and sound effects in the 1960s and 70's

Not too sure what it was used for but i have had a play with it and this is what i have found...
On the rear is a 5 pin din socket with 3 wires going to a pcb. These then go to selection switches on the front panel to select input trigger mode. Each of the 6 vco sections can have one of the 3 input triggers switched on. That vco is then triggerd by a voltage on its input from either a sequencer or any other voltage output device / keyboard

Each of the 6 sections has its own course and fine tune pots and also 4 x switches for octave selection as per an organ. 16ft - 8ft - 4ft - 2ft - these cn be selected so only one octave note is played or any combination of the 4 at the same time. Also each octave switch has a pan pot to make it a stereo output as well as its own volume control
I have managed to get 5 of the oscs to work but one did nothing. Will want the switches and pots cleaning/repairing to get it all going so i am selling strictly as spares or repairs for parts or restoration

On the pcb there are 6 parts each with some sort of voltage to frequency converter ic
Built into an open sided metal frame. Gone rusty on the frame but front ok
I am not sure what this would have been used for when built but basicly if you have a mono syth with a voltage output onto one input you can have 6 osc's play at the same time and tune or detune to make polyphonic like playing a chord and 4 x octaves can be played at the same time... : /
Dont know if any good to anyone but didnt have the heart to throw it out!
No warranty diue to age and the fact i dint know how to use or test it"
