2SK170 + 2SK170 + 2SK170 + 2SK170 (BL)Toshiba Super Matched Quad (4 ea) J-FET N-Channel Audio Transistors………. 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) and voltage (Vgs) are then measured quickly on a calibrated Agilent 34401 6-1/2 digit meter. FETs are matched to within 0.1mA Idss AND 4mV Vgs. In many cases, the matching is within 0.01mA and 1mV. 7-9mA Idss Range Order over $200 gets 5% discount (remind me when you order)………..
