source: Facebook.



after the RE-303, RE-606, RE-909 we have the RE-808 replica to build.

its an replica, which means 99.9% of everything is a replica - the pcbs, the case, the parts.

the only difference are replacement tactile switch of the sequencer.

but you can repair your TR-808 with the RE-808 parts.

1CPU mounting

As you can see you also need to do a jumper wire between the solder point marked A on the pixie cpu and pin 10 (!WE pin) of *any* of IC 7,8,9 or 10 (they’re all connected to the same signal)
Please note:
* This is on the back of the 808
* you solder the pins on the cpu on the “wrong“ side
* the jumper wire can be soldered directly as it’s just one wire, I use a pin header and patch cable here mainly during development as I can easily remove the cpu without having to desolder anything
* as the cpu is upside down, make sure you connect the midi wires the correct way!
* as always - pin 1 and 42 is unused and can be left unconnected (pin 1 is the hole with a square pad)

2PSU 

Do not fit the DC jack on the PSU circuit board. Its not used and it is not wired correctly.

use a cable for the jack as shown for example
