Hi,
I have measured up and grouped a batch of LSK170 jFETs, the Linear Systems improved second source equivalent of the Toshiba 2sk170 low noise jFET
I have pair matched.
Pricing for UK buyers:
unmatched LSK170 . . . . . £0.70 each i.e. £1.40/pr. . . sold out
<10% matched pair . . . . .£0.90 each . . sold out
<5% matched pair . . . . . .£1.20 each . . sold out
<2% matched pair . . . . . .£1.60 each . . only grades A & C left
1% matched pair . . . . . . . £2.00 each . . only grades A & C left
<1% supermatched pair . . £2.50 each.
They are available in A, C or C+ groups. All B grade stock is sold.
A = 2.6mA to 6.2mA Idss = pin compatible to 2sk170gr
B = 6mA to 10.5mA Idss = 2sk170bl . . the B grade is sold out.
C = 10mA to 20mA Idss = 2sk170v
C+ = 20mA to 29mA Idss ~= 2sk369v
C+, 20 to 30mA, are only available in:
<1% Idss @ £2.00 each
supermatched pair @ £2.50 each
All the cheaper ones went very quickly.
The <1% supermatched pairs will be <=0.5% Idss AND <=1% current matched @ ~ 25% and ~50% of Idss at the SAME Vgs while in thermal contact.
Postage and PayPal fees extra.
Non UK delivery addresses will incur a considerable postage and handling charge.

Andrew,
I would like
8 pairs B @ <2% matched
2 pairs C+ @ <1% supermatched
Same questions as Alan.

I bought from the Group Buy and effectively imported them from the US to the UK.
I can re-export back to the US, but you have odd Customs rules on letters and packages. It will cost a lot more.
I can use cheques or bank transfer for all UK transactions. That's why it's convenient having got them into the UK to keep them here.
I have found Paypal to work very well for foreign currency transactions.
I will do what the customer wants.
You just have to pay the bill.

Andrew, could I have a quote for:
8 supermatched pairs of Group-B jfets
24 unmatched Group-B jfets
..shipped to Greece and paid via Paypal?
Thanks in advance.

Don't clutter the thread.
I have sold hundreds in the previous 10months and not a single post shows in the thread.

We didn't mean to clutter your thread.
I guess it'd have helped if you made this clear in your first (or even third) post.

Andrew,
I need 10 pairs of 2SK170BL with Idss >= 9mA for Mihai's RMI-FC100 AMP.
They will be used in the input differential.
They shall be 2% matched.
Do you need any further information?
Best regards - Rudi

Andrew,
I found another hint in Mihai's thread:
The SK170 must have the same Idss>=9mA and must have the same Vgs +/- 1mV at Id=6.25mA.

Hi Andrew I tried to PM you but apparently your PM inbox is full and will not except any further PMs.
I'm interested in buying a few 2SK170.
Cheers

Hi Andrew
I would really apreciate if you could send me 30 pairs matched at 1% B grade
I would also like to have 10 pairs of <1% supermatched pairs of A grade
Please PM me so we can continue by e-mail
Best regards
Ricardo
PS: I must thank you again for your help in developing my new LMOS power amp..... It will be a blast.
