The middle lead on each volume pot is the "post pot" hot out for each sound
which runs to a common output bus. You can connect a lead from this to the tip
of a jack, and a lead from the ring of the jack to ground (lot's of stuff is
connected to ground on the board, the ground line runs along the top of board
above the volume pots) and you've got and individual out for that sound.
Extra credit (this is what I've done)...
1. Get (5) 1/8" CLOSED CIRCUIT jacks from radio shack (1/4 won't fit inside the
little 606). Closed circuit mean that a singnal will run through the jack and
back to the board when nothing is plugged into it, and will stop running
through when you plaug something in). Note that I've heard of people using 1/4"
jacks in a "breakout box" for this, but I wanted my 606 to keep it's beautiful,
compact, little batery powered self as simple as the gods made it, so I use
1/8" jacks with 1/8 - 1/4 adapters...
2. Cut the middle lead on the pot (this is a big pain in the ass, cause there's
not much room to work, best way to do it is with a Dremel tool or CAREFUL power
drill work with a really small bit - or removing the soldier and bendng the
lead).
3. Study the closed circuit jack to figure out which binding post (there should
be 3 binding posts) should go to the pot (this is the post that's always
connected to the tip of the jack) and which post should be connected to the
circuit board where the pot lead was disconnected - remember, just the middle
lead from the pot. If you're a newbie with this stuff and it sounds confusing,
remember the sound goes from the pot to the board, you want it to keep going to
the board when there's no plug in the jack, and you want it to go to the tip of
the jack when there's a plug in the jack. Study the mechanism on the jack and
you will understand. Also, you still need to hook up the ground. to the ring of
the jack.
-Now when you hook up the individual out, that sound will come out of the main
outs (a-la 909, etc).

ps, 606 hi-hats are priceless, sooo >. Plus, I enjoy getting
strange looks from people when they see me commuting on the train with my head
phones and full attention plugged into this little Coleco-vision
Football-lookin' thing (something I can't do with a "man's synth").

If you have the tools, you can unsolder the middle terminal of each of
the pots (except accent). Then you need the three terminal-type 1/8"
jack. Solder a wire from the hole on the circuit board you've pried
the center terminal from, to the terminal on the 8th inch jack that
goes to the tip conductor.
Then, solder a wire from the other non-ground terminal on the 1/8" jack,
to the wiper (center) of the pot. If you've done this right what you've
done is made it so that when you insert an 1/8" plug, the plug sleeve
gets ground, the plug tip gets signal, and the plug push the tip thingie
in so it breaks the connection between the 606 PCB and the wiper on the
pot.
If this isn't excruciatingly clear, then desolder the wiper, solder
a wire to it, solder a wire to the ground trace (the edge of the PCB), and
solder a wire into the hole you pulled the wiper from, and then experiment
with hooking it up to the 1/8" socket until you get it to cut the signal
into the mix, and get a signal output on the jack.
Or you can just solder a wire to the top of the middle lead on the pot,
and another to ground (the trace at the edge of the circuit board.
Best to use something like thin stranded wire, and leave some slack (2 inches)
so you can get everything put back together without wrecking anything. When
you put the circuit boards back into the case, take the knobs off of the
pots, shove the wires in next to the pot shafts, and then gently put the box
back together before putting the knobs back on.
Make sure before you reassemble the 606 that the start stop button is in the
lid of the case -- it falls out when you take it apart, and you need to take
the er apart again if you want to put it back.

Message 3/3 02-Dec-02 @ 03:48 PM - RE: 606 mod schematics
I'm a bit more interested in some of the sound functions mods. A buddy did a gnarly series of mods on the kick, amongst other things and said that it can adjusted to eat an 808 for fatness, maybe even rival a 909 for thump. All the sounds can be tweeked out, but you either need a new case, or a separate box and an umbilical. Unfortunately this friend is impossible at best to get ahold of so...that is why ask if anybody has ideas of where to look for mod schematics. Thanks again. Yes the 606 kicks royal ass.
