How to Install a LTC1799 Precision Oscillator in a Korg EM-1 Electribe

hi !
in this instructables i'll show you how to instal a GetLofi LTC1799 precision oscillator kit ;

First sorry for my english, its not my language so i do what i can :))

I bought a kit from us one year later for my Korg EM-1 , i was searching on how to install it , but theres nothing on the net about it , except a video showing you how it works once you already install it; The video was made by GetLofi, and i thought that they wil answer me if i asked them how to install it....but after trying to send them a couples of mails with no answers , i decided to do it myself;
the reason i wanted somebody to explain me how to install it is that the Korg EM-1 is full of different chips, and some make undesirables sparkles when you touch their pins....i didnt want to act as a circuit bender on a machine that i can sold 150 euros , by testing connectors everywhere and finally (maybe) found something; But actually thats what i did, and i also found interresting bends in the korg Em-1 (that i will show you in a next instructables :) )
For people who are wondering how the precision oscillator works , it affect the pitch on devices, such as grooveboxes, gameboy, synths and drum machines, cleary it overclock or underclock the device :)

Tools :

-A Korg EM-1
-A ltc1799 precision oscillator kit (or even just the pcb)
-soldering iron, copper wire, tape , screwdriver to open yr electribe
-Patience :)

Step 1: Open the Korg EM-1

i didn't got pics of this part , but you will see its pretty easy , as the screws on the back plate are the same than the ones on the PCB ;
the korg is divided in two PCB , the one which interest us is the first one you will found when you put off the back plate. go gently , especially when you take off this pcb : the potentiometers are quite long and are really annoying when you put the pcb off; maybe the on/off button of the electribe will stuck it , just push it and you will get the circuit board;

Step 2: Checking the Solder Points: THE CLOCK

so here are the soldering points ; the precision oscillator from Getlofi got 5 connections : 5v , out, ground, and 2 for the potentiometer
You can found how to wire it here : http://www.getlofi.com/wp-content/uploads/2008/10/2_LTC_Instructions.jpg
to found the clock, just take a look at the big chip on the left side of the board; the point is the one i show you on the picture;
as you can see it would be pretty hard to solder something on this chip, the pins are really tiny !! So i figure on how to wire it , just look  the back of the pcb , and you will see a solder point (see the second  and third picture) no problem to wire this one !

Step 3: Checking the Solder Points: +5 Volts

theres a few +5v points on the circuit board , all aready wrote on the pcb, so no problem to found this ;)
its important to found a source of power who power off when the machine is off ; Korg EM-1 is off the voltage is off too on the +5v point i choose on the picture .

Step 4: Checking the Solder Points : the Ground

Theres thousand of ground points you can solder on the board, as you can see on the pictures ; i choose one on the upper back side of the pcb (the black wire) ; but you can choose others theres no problem

Step 5: Place the Pcb, Potentiometer and Switch

once you finish to wire the precision oscillator kit to the korg em-1 , solder the two wires to the potentiometer you could found inside the kit (if you dont bought the kit but just the pcb, a 500k pot will be fine); you will have to hook up a switch to the "out" wire of the LTC1799 pcb, so like that you can switch on the electribe without make it freeze on the loading process; i choose to place the potentiometer and the switch on the faceplate of the korg EM-1;
after that, just put back the screws and ........done !!!! you can enjoy your precision oscillator !
for my part it just work well, i have to add some resistance to the wire because the system tends to glitch and freeze at very very low pitch , thats normal and on get lofi video description you can see that it glitch and freeze at 3k of resistance; the resistance supported depend on what kind of device you are using

hope you enjoy this instructables , if you got any questions just ask ;

Merry xmas and happy new year to all !
