2SJ74 + 2SJ74 + 2SJ74 + 2SJ74 (BL)

Toshiba Super Matched Quad (4 ea)

J-FET 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 in pairs to within 0.03mA Idss

AND 4mV Vgs. In many cases, the matching is within 0.01mA and 1mV. 

We have bags of matched P-ch pairs (7.0 to 9.9 mA range). Buyers will receive 

the tightest matching available, prioritized by Idss. Single shipments over $200 get

a 5% discount (remind me).
