Luvdunhill -

Thanks very much for editing my order on the wiki. However, I would like 10 LSK-170 Grade A, not Grade B.

Thanks again,

Karl

 

[AndrewT]

are you able to get a 1000 price for the To92 package?

 

[audiotony]

Just updated Wiki for:

4 x 2sk389 "B" TO-71
20 x 2sk170 "B" TO-92

thanks,

Robert 🙂

V is best, Bl next, and GR will do in a pinch.

John Curl just said this about selecting Jfets for his JC-2? and clone.
The same may apply to many of the circuits we plan to use the LSKs for.

Wanted to join this GB but wonders how to get the P-type?

 

[AndrewT]

I believe that LS keep promising to release Pchannel, but I suspect production problems are delaying.

I believe that LS keep promising to release Pchannel, but I suspect production problems are delaying.

Maybe market issues matter too? Why did Toshiba quit these models and why does LT find it worth taking up production? Is there a sufficient market demand, and if so, is it sufficient also for the P types?

I posted 1000 price breaks for the LSK170 TO-92 on the wiki. Looks like the sweet spot of getting "free" devices is around 630.... so, looks like I'll have some freebies to toss around. 😀

At this point, I'm planning to close this group buy on:

Thursday, July 24th at 12:00 noon CST

and will begin to send out invoices. I am inquiring about lead times and packaging format today and will have more information on that later.

I just posted 14 of the LSK170 (B) on the wiki. Seems like I got my order in just in time. 🙂

 

[audiotony]

added:
2 more lsk389
10 more lsk170

for a total of 6 and 30
thanks,

Robert

 

[Looneytunes]

I'm in for...

40 x LSK170B (TO-92)
6 x LSK389B (TO-72)

Thanks,
Looney

 

[stoolpigeon]

sorry, I may have stuffed up the wiki trying to add in:

LSK389 (TO71) 4 pieces of each grade (12 total)

Hi,
I have changed my order if you can get those 1000 off prices.

If not then I'll revert to previous quantities.

What's the hurry?
it was said we keep open if we hit 500 to see if we can get to 1000.

 

[claudio]

If the 1000 off prices are confirmed, I will increase my order too.

 

[Looneytunes]

I just bumped up my request to...

40 x LSK170 B (TO-92)
10 x LSK389 B (TO-72)

Thanks,
Looney

Sorry,
I put my order in to prototype line at the bottom of wiki page, and am afraid to muck it up further.

Could you adjust it?

Thanks.

yup, I'm starting to agree that perhaps we should wait a bit longer.
