Here is my Mouser cart for euro DSG: https://www.mouser.fr/ProjectManager/Pr ... 3a547e2afd
It does not include:
2x SIL header 4pol 855-M20-9770442
6x SIL header 5pol 855-M20-9990545
4x Switches SPDT Expo 108-0044-EVX

Jacks and 50k pots that i order from Thonk and Tayda.

Mouser project for the Euro NCOM:

http://www.mouser.com/ProjectManager/Pr ... 15573ed46e

I have not ordered yet, so there is no guarantee this is 100% OK. Let me know if you spot any issues.

Notes:
  • Includes expensive 0.1% tolerance resistors for R3, R10, R12, R21, R22, R23, R24 (249k) and R20 (499k). Replace with 1% if you are on a budget.
  • Includes WIMA caps for CX and bypass positions.
  • Does not include pots, jacks, headers/sockets!

Complete MOuser BOM for Res EQ
This project has both 7x C0G and 7x WIMA .01uF as bypass caps in it.

I'm piling up an R*S basket at TME and I can't find anything named precisely CD4520BE; the closest is CD74HC4520E. The pinout, functional diagram and truth table look like they match the CD4520BE datasheet up on Mouser but it's mostly above my head. How many letters around the number do I need to get right? gaaah :help:

If you look at the datasheet you'll note that the 74HC runs on a supply voltage of 2V to 6V, CD runs at 3V to 18V. ie 74HC runs at low voltage, Ken Stone has useful info here:

Looks like TME don't have anything suitable. :sadbanana:

Thanks so much for this

Would these cheaper 0.1% resistors be an acceptable substitute?

What size standoffs should I use for the EuroSerge? 11mm?

Good find, but only for R20. The 249k version of that resistor is not in stock (for the other positions).

Yes 11mm

Edit: I built my NCOM with these parts and it works perfectly. A few things are missing like pots, jacks, SIL pins, but the essential is there.

Having a hell of a time finding 5mm 2mA LEDs that are somewhat bright. I ordered these and they fucking suck;

http://www.mouser.com/Search/ProductDet ... -HLMP-4719

They're weak as hell.

You can attenuate the brightness with a higher value for RLED resistors and test it on a breadboard with a 5V source (from a jack for example).

Edit: I think that I did not understand correctly. :hihi:
This model is powerfull but yellow is not disponible at Mouser for the moment:

Those exact LEDs are in my SSG. I was just hoping someone had another source for brighter LEDs.
:deadbanana:

*edit - looking for a pair for my DSG.

Looked everywhere for the yellow. I guess I'll have to wait for the duration of the lead time. If anyone has a set (red and yellow Kingbright), I'll pay double the price and shipping.

I'd look for amber, not yellow.

I have missing notions about trimmers.
I found the brightness that I like for my leds but it's not exactly the same on each led, so trimmers would be handy to set it perfectly but...
I'm not sure, does a trimmer go from to 0 resistance to the resistance announced? :hmm:
I'm affraid to burn the leds setting the leds brightness with trimmers...

The Zeners on this cart are too thick for the PCB holes. Also, there's not enough room to squeeze the 220pF WIMA cap in between the resistor and socket without floating and angling it. This is difficult to do, as the legs are really short.
