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.

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.

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.
