Re: Buchla 200X serie 208X build thread
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....

I ve just ordered the last week
Order the Friday before 2pm,received the Monday before 1pm
Usa to France ,if your basket is above 50eu =free shipping,choose the option fees paid by mouser at checkout.Fast and no surprise at the delivery Pic of a basket of only 22eu (then a shipping has to be paid)

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
https://www.taydaelectronics.com/potent ... c.html?p=2
Small bear is great
http://smallbear-electronics.mybigcommerce.com/
Synthcube
https://synthcube.com/cart/
In Eu
Farnell
https://www.farnell.com/
https://www.musikding.de/
Digikey in US
https://www.digikey.fr/
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
https://www.ebay.fr/itm/1-PC-Cardedge-c ... 3809008169
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 .

Re: Buchla 200X serie 208X build thread
What is everyone planning to use for the VTL5C3 Vactrols? I've read that the decay on Xvive versions are not very good.
Re: Buchla 200X serie 208X build thread
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 :

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