Toshiba 2SJ74 + 2SK170 MATCHED PAIR 0.1mA-match (9-11ma Idss Range “B” “BL”)
2SJ74 + 2SK170 (BL) 9-10mA RangeToshiba 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.Combine orders over $200 get 5% discount (remind me).A flat $4.00 shipping charge with tracking for ANY quantity ordered. International order shipping typically $38 (ask first). ………. Brand New – From Original Boxes & U.S. Authorized Distributor TO-92 Package – Uncut – Unsoldered – Fully Tested Sale is for 2 pcs (1ea 2SJ74BL and 1ea 2SK170BL, Idss-matched) First Class Mail with tracking to 48 states. Inquire for other locations. 30-Day Returnable only if not as described, and must be uncut and unsoldered.
Toshiba 2SJ74 + 2SK170 LAB MATCH QUAD to 0.1mA (7.0 – 9.0 mA range “BL” “B”)
2SJ74 + 2SJ74 + 2SK170 + 2SK170 (BL)Toshiba Super Matched Quad (2 ea type) 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 0.1mA Idss AND 10mV Vgs. Most eBay audio FET resellers do NOT match for BOTH Idss and Vgs.In some cases, the matching is within 0.01mA and 1mV. Buyers will receive the tightest matching available, prioritized by Idss. ………. Brand New – From Original Boxes & U.S. Authorized Distributor (circa 1996-2012) TO-92 Package – Uncut – Unsoldered – Tested – MatchedSale is for 4 pcs (2ea 2SJ74-BL and 2ea 2SK170-BL). Idss is 7-9 mA range “B” or “BL” First Class Mail (USA) $4.00. International First Class $18. Insured Intl Priority $42 30-Day Returnable only if not as described, and must be uncut and unsoldered.
