This is for the group buy of the Fastron Inductor of JG's filter buffer for ES9022 GB..

I have a meter and could match these, then send out? I get free mouser shipping if the order is more than €75, but postage from me onwards would have to be figured. I can't add my name right now to the sheet (phone access atm)......

Would it make sense for Fran to do matching and distribution for the EU members?
Happy to do that, or even match all and send a pack to the US for further distribution - but I can't see that being viable.....

I am more than happy if Fran takes over the GB.
FWIW, if I order from Mouser, the sales tax will be around 9% and shipping is around USD 10. The overhead is approx USD 25, spread it across the board will be less than 25 cents per unit. The saving is not likely to be significant one way or the other.
While we are at it, I wonder we should also purchase the remaining parts. I suspect the inductor might be the heaviest single parts ......

Let's swap EU orders to Fran.
Just wait 2 weeks and have a look a the number reached to see if it makes sense.
If we could add other parts, I'm sure it will 😉

I just checked the main GB, only 16 out of 66 are for USA, and 2 from Canada, a total of 18 buffers from NA. So, it is probably better to have Fran to purchase from his end then. Unless Fran objects, he will be the coordinator of this group buy 🙂
Gulp!
I haven't run a group buy before, so might need a little hand holding.... But should be ok. ;-)
Just to add, the lcr meter I have is one of those €40 ones from ebay that salas mentioned in the other thread. I don't know exactly how accurate it is, but repeat measurements show pretty ok precision. I should think that would be ok for matching purposes?

From what I understand, absolute accuracy isn't very important. It is the matching readings of the inductors. So, I am sure it will be good enough.
Thanks,

Yes, from what I've understood the relative valour is important not the absolute one.
18mH is the ideal rating value, but this could be OK if you read 18.3mH for both parts of the twin.
It works too if you read 17.9mH or 18.2mH 😀

It helps if people start to do a list with :
names, quantity, country.
Help Fran to help yourselves.

"The coil has to be put in a small Mumetall container."
Is there any source for the mu-metal container?

Would those that have signed up here already be interested in turning this GB into one for the SMD components as well? The only thing is that I think I would need to get all the stuff together from mouser - I don't think digikey does shipping to here?
