From Christopher_List@sonymusic.comThu May 18 10:46:20 1995 Date: 18 May 95 9:13:51 EDT From: Christopher List To: analogue Subject: An easy <<606>> mod for y'all... ...individual outs 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). -Topher 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").

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 fucker apart again if you want to put it back. > 2) the inner ring on the jack i'm guessing is the where one end of the > ground lead is connected, but then where does the other end go?
