Hi all, thanks to Patrick I am starting GB for Limited Edition SMD Folded Cascode CEN IV from XEN audio.
LINK to thread for technical discussion.
This GB is limited to 20 pairs and will come as a KIT with all matched transistors, capacitors and resistors needed for assembly.
When we reach 20 pairs I will send requests for payment and start ordering transistors for matching.
After matching transistors I will order the rest of needed components and pack everything at least as good as the last GB I did, so you will have no trouble when assembling PCBs.
Between all the ordering, shipping times and matching 500+ transistors it will take a while, so I will report my progress as often as needed, but I hope by the end of year all should receive their KITs...

I will update SPREADSHEET, just leave your username here and PM me your contact information (paypal email, and shipping details)

A huge effort to take on matching some 500 devices of different types (JFETs, MOSFETs and BJT).
Each type requires their own matching setup.
And then the sorting and packing afterwards.
I can tell you it is really a mammoth tasks.
A remark on the Power Supply
The protos that Fran auditioned are using separate +/-15V power supplies for best performance.
In principle, one can adapt the circuit to use +/-12V rails, at somewhat higher distortion.
It should be decided upfront whether 12V or 15V, but it should apply to all 20 pairs.
(Component values are different.)
