We have been approved by GB members, as well as others, whether we still have some regulator Mosfets left.
We bought 50 each (P & N), and only just managed to get 22 sets of 4 to cater for the subscription.
The remaining are quite a way out from the others. The Vgs spread is not small
So as much I would like to, I have no more to offer.
The rejects will be used for other test purposes for which matching is not required.
I encourage you to start a new GB of say 100 FETs or more.
That way your matching will improve with less rejects.
Also means more work, unfortunately.

Digikey has a long lead time: shipping in October ...
I have not been able to find better offerings so far
I am willing to get a GB going by ordering 2 x 100 Fets, but I need other volunteers ...
I am am in the process of almost completely rebuilding my "shack" at home so I cannot do any work there for some time

We have sent to Horio & ichiban as small packet registered today.

Happened to us twice in 2 years, both times with the USPS.
So the HK Post was not at fault.

PS Fedex from HK to US is more expensive than the FETs.

I'd be interested in a matched set.
Don't know, however, if I have the equipment to do matching myself, without "tutoring".

I don't have the level of equipment as Mark but should be able to match at the operating condition. I will match them from the a pool of 50 pairs. Hopefully, I will get similar yield to get 20 sets (2 x SK3497 and 2 x SJ618 per set). I assume each person will want one set for ONE F5X, here my lame book keeping:
pchw (Obviously, I have the first dibs
) x 1
chalkandalk x 1
CamAm Man x 1
JBdV (I assume Jan will join from the interest expressed previously) x 1
Feel free to edit and adjust the amount accordingly.

Thanks, pchw, for your willingness to perform this GB. Appreciated!
Maybe you could open its own thread in the "Group Buy" section?

Here is the group buy thread http://www.diyaudio.com/forums/grou...j618-euvl-f5x-other-projects.html#post2638207
Please post you interest there.
Thanks!!
