sbelyo Posted March 6, 2017 Report Posted March 6, 2017 http://www.ebay.com/itm/322416989057?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Looks real in the pic and has a pic of a lockyz output from the curve tracer. Gets good feedback and all. Still no real way for me to tell from the pics. I was hoping to buy a set and ask one of you more experienced users to test them for me to see if they meet original specs.
Bespav Posted March 6, 2017 Report Posted March 6, 2017 Yes, i have buyed 2SK163/2SJ44 pairs from this seller, they was original and very well matched.Matching checked with PEAK Atlas DCA75And gate capacitances checked with simple transistor tester (as a marker of datasheet specs):Combination of the transconductance and gate capacitance are unable to be counterfeited together. It would be great to check intrinsic device noise, but i'm too lazy for that.So i hope, those 2SK369's are original too.
sbelyo Posted March 6, 2017 Author Report Posted March 6, 2017 sounds good... They appear to be an honest seller
