Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in Transistors
These Toshiba dual JFETs are out of production. Nobody knows why. They are popular with DIY audio fabricators, and even Nelson Pass (designer of Threshold, PASS, and First Watt amplifiers) uses them. The problem with JFETs is that they are sensitive to static electric discharge. Poor storage, poor shipment techniques, overheating, etc. causes many of the remaining stock of these valuable devices to be damaged. The ones that do survive have frequent intermittent problems with noise and distortion. These devices are a treasure that audio fabricators need to cherish and protect.

All 4 of the 2sj109s I received tested like dual p-channel JFETs, each transistor was well matched matched and within the BL spec on my DCA75. The fakes I’ve received in the past from other sources (in the USA!) weren’t even JFETs.
