Ive updated the psu/Boat 4UX mouser basket ,new external brick

Missing a trace card 8,it’s happened when we have reduced the pcb ,to not touch the reverb frame
Pic above /below ,just add a small wire.

One TL074 added in the new card 12 bom

Edit the 14 April
Aux card pcb :R20:47k

Edit of the 7 April 21

CX1 /CX2 10uf on the MB pcb ,are voltages filter electrolytics caps ,added for the seq reset, there are on the seq card 1 bom section .
CX5 is 10 nf (forgotten in the last bom update )but it is ordered in the basket,sorry

If you choose the option to have the reverb mix level cv ,in the headphone (monitor) circuit,too
Use R73 or any resistor above 10k for R73X ,this resistance will be in serie with the trimmer TRX11 to calibrate the dry audio signal return following your wish.
And make the jumper .
The pic of the motherboard modification for my new card 12 here

29 03 21 ,I ve found the flashy leds,updated with the low light better leds.
Ive updated the 10 pins power connector for this one better quality imho
https://www.mouser.fr/ProductDetail/798-CR6-10S-3.96E

HARDWARE
A note about resistors sourcing at mouser,the day of your order .
If ref 603-CFR-25JR-52-xx
is not available you can swap with
603-CFR-25JB-52-xx
The goal here is to have more than 10 resistors of the same ref to have the quantity discounted .0,085 to 0,042 ;)


I like the tayda electronics pots
Small bear,Thonk is fine,too.

Cheap Colored caps

Seeing all these BOM's are for Mouser...has anyone ordered from them lately? (as in after Brexit?)
What are the shipping times?

I had an order at RS-Components which took 5 weeks to arrive due to stuff coming from their UK warehouse....

The links are always in the post 1

Open a mouser account ,load and save each projects,then you can manage your final order easily
For a project like this ,a local store can good,for some parts.

I like the pots at tayda ,you will find plenty of parts ,which are missing at mouser by exemple the colored caps,ic sockets,molex connectors ,some e switch toggle,etc

Small bear is great

Synthcube

In Eu
Farnell

Digikey in US

For the reverb tank,in EU

https://www.banzaimusic.com/accutronics-1bc2e.html

For the blue 56 edge connector not included 2x28 pins

Google ebay 56 pins edge connector 2x28 pins

FOR BUNDLE KIT WITH AN ALUMINIUM PANEL ,NO 56 BLACK CONNECTOR INCLUDED ,BUY 2X BLUE 56

Example

TIME TO LEARN A LITTLE ABOUT PICKING SOURCING PARTS

Remenber ,you will use a lot the switches when playing your 208X!

For the toggle switches ,the best are CK/NKK,(In the MB V5 bom)APEM
E switch (mouser ,tayda )are fine ,cheaper,or you can use generic Banzai,small bear
Take time and check the bom ,learn from the datasheets

We need

DPDT ON-ON-ON
SPDT ON-OFF-ON
SPDT ON-ON
SPDT ON-OFF-(ON)

SPDT SINGLE PÔLE DOUBLE THRU
DPDT DOUBLE PÔLE DOUBLE THRU

ON/ON 2 POSITIONS
(ON) for momentary switch

Check the size of the shaft,size of the toggle itself
PC pin,SOLDER pin ,THE BOTH ARE OK WITH THE 208X MOTHERBOARD (MB)

SHARE YOUR LINKS HERE THEN I WILL CHECK THEM

A note about resistor ,capacitor often it is cheaper to buy at least 10 parts than 1or 2 parts.
Example
10 x 0,12 =1,2 eu
3 x 0,45 =1,35 eu

Ive done the first direct order card mouser baskets ,card 1 ,card 2,psu,X parts ,fyi the ref for the resistor has been changed ,as the old ref are sold only by 200 now.
Feel free to continue for the next cards 3 , 4, 5, etc and share your work,I will check it of course .

What is everyone planning to use for the VTL5C3 Vactrols? I've read that the decay on Xvive versions are not very good.

Hi,

I tried to make a Mouser basket for Card 3, but the resistors listed have to be ordered in multiples of 200 ! I'm pretty sure you wrote something about that but I can't find where ! ^^

Anyway, here's the basket :

I'd get resistors from tayda or even small bear. Very easy to order from tayda.

Ok, then I'll make a separate project for the resistors for all PCBs. It will be easier for me.

Basket for Card 4 (without resistors) :

Basket for Card 6 (without resistors), but the LM301 listed in the BOM is no longer available, could you give me the reference of an equivalent ?

Your card 4 and 5 links give us the same basket :hmm:
