[sdiy] What do people use for matched transistors these days?

Not quite "knock-offs" anymore.   SMIC make the wafers and JCET cut, package and test the discrete transistors, then sell them both under the JCET label but also supply many of the better known brands, releasing their fabs for more profitable ICs or power devices.

Obviously they don't make new masks for every transistor on the planet, but providing the specs are withjn the minimum and maximum bounds for each device it hardly matters.  There's probably a 2N...., BC... and 2SB.... number for what are effectively identical devices so there's already lots of duplication that can be avoided.

  *   Here's the thing. Any transistors you buy now are likely to be the much-derided "Chinese knockoffs".

  *   Today though the "BC548" that some dude in a shed in Shenzen
