2SJ74 + 2SK170 (BL) 9-10mA Range

Toshiba Super Matched Pair (1 ea type)

J-FET Audio Transistors (P and N)

9.0 - 11.9mA Range

..........

These JFETs were matched at a constant 72 degrees using a meticulous lab process.

JFETs are inserted into a custom 90-socket gold-pin ZIF test jig (30 devices per test). 

A well-regulated and carefully monitored DC supply voltage of 9.00V (not 9.01V) is

applied while FETs are allowed to stabilize for at least 5 minutes before testing.

Current (Idss) is measured quickly on a calibrated Agilent 

34401 6-1/2 digit meter. These FETs are matched to within 0.1mA Idss. 

Shipped in black static-shield bags surrounded by pink anti-static wrap.
