Nice!
With the stuff I pre-ordered from Visible Signals/@VisibleSignals, I will exhaust my own supply from the previous group buy and need to finally get more. …Though I might just go for a few direct from TI rather than trying to arrange a big/group buy in the U.S. this time around. (Not that I arranged the last one, but I did participate.)
Hopefully the minimum order isn’t 100 or more at TI. I’m sure their prices were the best over here in Europe when I last checked a few months ago.
I also gambled on LM6172s from eBay and ended up with fake ones. 
So I’ve now ordered 116 from Rochester via DigiKey and should be receiving them in a week or two. If anyone in the US wants to buy some of them, hit me up.
Hey, yeah, I might want to get in on that. Not sure exactly how many I need until Aladan posts the BOMs for his modules. But maybe ~15-20?
I’ve been working on them, really! I have a proof-reader who is helping now (thank you, anonymous proof-reader, you know who you are).
LM6172 counts:
I can finally offer something to this thread! 
I picked up some XD1881’s which are drop in replacements for the LM1881’s, but at about 1/10th the cost. It looks like the thru-hole version from TI are now obsolete.
I bought 10 for 10€ about 4 months back on eBay. Took about 2 months to arrive and with no immediate way to test them, I didn’t qualify for a refund once I got some Cadets built 
Just plain stupid of me after reading so many similar stories on here.
Glad to read you bite down & put in an order for legit ones. I’m really glad I did it, its changed everything as they were the last thing I needed but stupidity hesitated on 
Nice one @VisibleSignals for posting the LM6172 count on your modules, I’m sure a few of us here are gearing up for their arrival 
@Fox, cheers for the tip, I’m really curious to see this chip in action. Have you been able to compare it in two of the same module or on a breadboard circuit?
Hello everyone 
For anyone in Europe who needs any LT1251CN or LT1256CN ICs, I bite the bullet & bought 25 of each to get the lower price point. They’re used in the a few of the higher number #Cadet range. The 1251 is also used in @VisibleSignals’s RGB Matrix Mixer.
I’ve also got well over 100 of the PJ302M right-angled jacks that I sourced directly from #Thonk & plenty of LT6172 Op-Amps so if you’re in Europe (or elsewhere for that matter), send me a message and I’ll check the postage costs or pop over to www.post.de for letters & small packages. Www.dhl.de/en has an English option for info & such.
To most of Europe a tracked letter under 50g costs €4.20. A tracked padded envelope up to 500g costs €6.30.
There’s a well stocked electronic component shop 5 or 6 mins by bike from me. Online orders can be picked up from their door so if you need anything, I’m happy to include them.
Will write u when i checked how many i could use
Hello, was curious if anyone could recommend these ferrite beads from Tayda for LZX/etc DIY?
76Ω as opposed to 68Ω recommended in the Castle BOM, wasn’t sure how much that mattered?
Really weird coincidence. Just yesterday I was going to post about those exact beads. I was making graphs comparing the cutoff frequency for both the 68R and 76R beads with the accompanying 10uF caps and got tired. It was really late. 
Yeah, they’re fine to use.
If you need more than 100 though, Mouser’s price break is a better deal for the 68R but the minimum shipping is $7.99.

hah, awesome, thanks!
Okay, with some orders from Visible Signals and Syntonie and some other upcoming things, I think it is time for me to re-up my LM6172 supply.
@mrfang, still have any from your Rochester lot? I’d be looking for 20–25, depending on per piece cost.
Or does anyone else want to go together on another group buy?
Update: sorry, @sean , I don’t have enough left to offer any.
I’ll soon be ordering some more LM6172 ICs if anyone in Europe is interested in some. There’s some great news on Syntonie’s Modulargrid page 
Checkout the VU005 & there’s a couple of others surprises too 
@syntonie, are you going to create a thread on here regarding your new modules or is the info on #Modulargrid the result of a successful cyber hack of your servers & leak of your closely guarded corporate secrets 
Just listed them today
VU006 is audio rate so it doesn’t require LM6172, there is a few in CBV002/VU005 though. Will do a thread once everything is ready 
Re: VU007 Encoder
…however a RCA sync board could be designed and put in place of the existing power/sync board if there is any interest.
Going to jump the gun here and say, Yes, please!
The race is on. 
Anyone order LM6172s from these folks before?
Because, yeah, that’s a good price if they’re legit.
they have a Anti-Counterfeit Policy | WIN SOURCE
but I’d say, buy a few to see if it is real, then buy bulk?
ps: in the specs, they have this: “Fake Threat In the Open Market = 46 pct”. I wonder what that means
