I stole the above photo from here This is a real monster from years past! What an organ - sold as a portable but then by today's standard perhaps the phrase is luggable. It's quite heavy and bulky to handle - relatively difficult single handed but not too hard to assemble.
The dark red and pale green squares are tabs they add the pipe lengths, note the lower keyboard... an octave of reversed keys, then an octave of grey keys then the normal set up. This is neat because the black keys are bass notes and depending upon a tab setting the grey keys can be either an extension of the bass keys or an extension of the normal white keys, the distinction being indicated by the small red lamps shown between the two manuals.
The dangly thing under the lower keyboard at top C is the knee
lever. This device seems quite obscure, you have to know how to kick
it in. It works in conjuction with the green tabs on the upper manual
only. The Booster tab must be off, when moving the tone boost lever to
the right it brightens the sound. It seem that it takes the tone to that
when the booster tab is pressed.
The organ is in two parts, the organ itself and a remote box housing
the reverb and power supply. My unit came without the additional box, foot
pedals or swell pedal and I had to make a power supply. I don't miss the
reverb - it probably would have got replaced anyway. It seems like the
power supply is the main problem with these organs, as in non existent.

I think John Lennon (I have a photo of him with a single manual version),
Question Mark and the Mysterians with their hit from the 60's entitled
96 Tears, Ray Manzerk of The Doors and Rick Wright of Pink Floyd (thanks
to Mike Cornett).
Putting the key levers (lifters) back in place requires full access
to the internals which is done by lifting the organ from its case where
you find a host of technological wonders. Sure it's a transistor organ
- but these must have been from the first batch of transistors ever made!
The circuit boards are mounted into wooden pigeon boxes - wires strewn
all over the place. Not an impressive construction - but then typical of
the time.
The output signal level is quite low making it susceptible to noise,
indeed the bleed over from the oscillators is quite noticeable - plus I
would expect that with light dimmers buzzing away on stage, so too will
the Farfisa.
One time at rehearsals I remember the guitarist could pick up the
most wonderful ethereal sci-fi type sounds just by getting close to the
organ.
Having now been made aware of the cost I've done some samples for the Ensoniq EPS16+ which I suggest is the better way of getting the Farfisa Compact Duo sound. Go see www.esqbase.de and look under organ, Farfisa.
For more information about this and similar organs go check out my net pal Robert at Combo Organ where you will find many very interesting things about these organs. Including a real circuit diagram of the power supply!!
Being something of a technical wizz... I'm now something of an expert
on fixing these beasts!
