I scored an entire 3000pc reel of Genuine Toshiba 2SK117-BL smd fets today!!! Now i need a project for some!
How about a nice fully balanced Diff amp input with CC and a source Follower??

Ebay ? You really sure their genuine ? These jfets arent exactly cheap and readily available, so scoring a 3k roll of them for cheap does pop up counterfeit flags for me.
Nope not eBay, scored them from work. I bought a bunch of surplus stuff. they have been sitting on a shelf for the last 10 years still in the Toshiba factory box, still sealed in the bag!! these are the real deal!
this is completely unrelated but i just so happen to be listening to orbital halcyon and on and on and i notice your username is zero cool lol
something is telling me to watch the movie hackers

I guess your not willing to sell a few. It'd be fun to put these against those 2SK331's i scored on ebay in performance and sound.
If you do decide to part with some please let me know.....I have a friend who would be very happy to have a few of these show up as a surprise 
I have no need for all 3000....hmmm wait a minute...Didn't Pass do something with 1000 fets??? hmmmm I wonder how big of a board I would need for 2 channels of 1000 fets each??
I am really hoping someone has some project ideas of what to do with these??
I will post something in the swap meet section about sales.

WHOOOOOPS...NOW i see WHY they have been in the warehouse so long... The BOX is labeled 2Sk117-BL the reel itself is Labeled 2SK711-BL oh fudge im so embarrassed....never mind... maybe the mods can delete this post....I am going to hide under a rock now...
Don't worry about it. Their still usable for audio amplification according to the datasheet. And anyone can solder a SOT23.😉
They are only 20Vds.🙁 Might be useful for pre-amp applications or cascode IPS, or even a nice quiet cascode CCS.🙂
SOT23 is nothing to solder, try SOT563 or SOT923.😛
In the photo, the devices in yellow are SOT563 duel mosfets...the VAS for this amp. You can see SOT923 at the top right, between the grey film cap and the 4.7K 1/2W resistor.
😀 I like using those small parts because they save much PCB space allowing for a tighter layout. You have to watch Pd with SMDs, in the case of the SOT563 mosfets Pd=100mW, 50mW for each element.
