Moog Music Voyager

Moog Voyager's back side opened

On the left there is the power supply (3rd party board) and a little power supply board that might generated the additional voltages not available on the power supply:
All cables used as ground are coloured green

In the big horizontal board on the right is the analog board. And the board left of it (the one with those many blue caps) is the digital board.

I spotted under the widest flat cable going from the digital board (bottom left) to the panel:

Moog Voyager's mid backside opened

There are more wires than inside a PPG wave 2.2 or 2.3 !

Moog Voyager's right backside opened

The big analog board (20 x 38 cm / 8 x 15 inches)

Moog Voyager's left analog board view

The left half of the analog board. This board does feature some labels like "Glide circuit" and "Oscillator section", ...

... but there is no label named "filter" or something like that.
The Moog filter transistors are constructed from the CA3086 transistor array. So the filter transistors are not descrete. If this is a bad or good thing depends on your personal view. See many long threads at certain web forums.
Anyway, the Moog Source also used one transistor array chips (a CA3046) as well for the needed matched pair of transistors on top and bottom of the famous Moog ladder filter. And we all know this didn't sound bad then nor today.
