RE-606

Build Guide:

BOM:

RE606_BOM_191022.xlsx (First version)

RE606_BOM.v1.3.2-RLS.xlsx (latest version with mouser part numbers)

Cases are bought by kumptronics

CPU was from pixie (included in the RE-606 pcb order) 

mouser card: (not approved from me)

https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=040a0cbc 

add the tactile:  688-SKQEAA 

(wrong here is the 22pF capacitor !!

also the 0.47UF is wrong - its bipolar in the mouser Bom instead of polar ) 

another mouser card is available:

• Mainboard

  • CR97 -> R97(4k7) and use C110 (1NF parallel)

• Tom board:

  • CR305 ->  R305 (4K7) and use C329 (1nf parallel)

  • CR308 -> R308 (4K/) and use C330 (1nF parallel)

Open

• The jumper wire strip from the alpha BOM was slightly too short, looks like it was updated in the latest BOM to 3 inch, but I would recommend maybe even getting the 4inch instead of 3inch :

  • 571-FSN-23A-8 (Mouser)

• The scale switch - while this is by no means correct, this will work - just need to wire it to the board, and its quite small compared to the hole in the cases etc

  • 611-SS-24E06-TG5P (Mouser)

Tipps:

in case you dont have the SCALE Switch and want test the RE606 with a Workaround (Bridge Pins instead of a Switch)

, you have to Bridge the switchchassis holes with a cable at the outer mounting holes (same in Re303 ) - otherwise the GND pads/traces of the Instruments  are not connected 

Discussion about the Scale switch:  http://23.235.199.139/~re303c5/forum/topic/514-unobtainium-re606-pre-scale-switch/?tab=comments#comment-12104

Install CR97 (1nF) and R106 from the bottom side otherwise the Mode Switch will not fit.

BU -battery   Wire port 28 (not sure what to expect here but I measured somewhere around 6VDC iirc)
6VDC    Wire port 30
15VDC    Wire port 33
5VDC    Wire port 34

Issues:

Issue 1: (see service notes from Roland to check the correct layout) 

please respect on the switchboard D404 is in wrong orientation, as described in the BOM

Issue2:

On the switchboard are the capacitor designators wrong labeled !!

C1 = C401  1uF/50V Electrolyte polar

C2= C402 10uF/50V Electrolyte polar

C3= C403 100uF/16V electrolyte polar

CPU update/firmware/bootloader

in case you want upgrade the firmware, you have to update the bootloader.

I´dont give support about the update processes since I bricked my CPU while updating it and ended in a installation of an original CPU
