I tried yesterday to get my hands on the FA3 but the manufacture is holding them with an iron grip. All I managed to get were a few samples for myself and a few others.

I can get FD2 SST-20’s but I don’t know if it would be worth the hassle as I would need to get 500+.

BlueSwordM recorded interest in 412 x 4000K SST-20 so far in a group buy thread he was running. He already made a group buy of 3500K, but 4000K has been on hold for a couple of months due to not being able to confirm availability of anything better than FB4.

Second Generation Silver Plated High Current Beryllium Copper Springs and 95+CRI SST20!

So, I’m here again guys with the BeCu spring groupbuy interest list. Only this is for the Part 2 GB with upgraded silver plated BeCu C17530 springs, instead of nickel plated springs. Just by doing that, we will be gaining a 5% increase in conductivity alone, which is nice, along with much better contact resistance. So that means even better spring for high current applications. Here are the specs of both the small and large springs: Small spring: Material: Beryllium Copper C17530 38% IACS S…

Perhaps FD2 is good enough to start trying to get a 4000K group buy in motion again?
