Hi,

Yes, I still have many more of the 2SK389-GR, 2SC3381-GR & 2SA1349-GR

But sorry no 2SJ109 of any kind, as I wrote in post No:1 in this thread.

Hi Pradio,

This is a tricky question. N & P complementary bipolar devices are more data-like each other than P & N J-FET's.
Only thing to match would be Hfe, but with emitter degeneration resistors, normally used, that is of no importance either....
Vbe and temperature variations of Vbe, is already matched from the monolitic design.
Se datasheets from Thoshiba on the internet.

Reminder:

For a limited period of only 30 days (during august 2010), I'll take orders from any members here as follows.

10 pcs 2SK389-GR at a price of USD 45.00 + 4.00 P/P = USD 49.00 total
20 pcs = USD 90.00 + 4.00 P/P = USD 94.00

Additional 10 pcs 2SC3381 or 2SA1349, or 5pairs 3381/1349 = + USD15.00

The transistors will not be measured or matched. IŽll pack them direct from the Thoshiba factory antistatic bag (where they've been in my possesion since january 1993) into the delivery antistatic bag.

Just send me a PM and I'll return my PP/mail-address.
Or I can send a request for payment, if you PM me your PP mail-address.

JohanB
