Japan mostly, but that is supposition on my part. I believe some of
those fakes were simply relabeled parts and not necessarily purposely

horizontal/line output transistors a hundred at a shot (like the Toshiba
2SC1172B or Sanyo 1308K). Then we started getting counterfeits that
would last minutes to days, then blow. We used to buy Sony SG613s in
bulk and never had a problem. Suddenly the next shipment would blow up
on plug in.


I had no idea it was so universal. I mean, until recently I thought the
problem was confined pretty much solely to voltage regulators, but
clearly it goes way beyond that. I find it all (the 'infection' of the
supply chain) deeply concerning.
