Up for sale here is this set of 10 (ten) brand new OnSemi KSA1381ESTU transistors. These are genuine OnSemi transistors, and are invaluable for vintage electronics restoration. They are great subs/replacements for a number of vintage transistors that can get noisy over the years. These will replace the following transistors, among others:

2SA537
2SA706
2SA818
2SA858
2SA896
2SA899
2SA914
2SA939
Many vintage Pioneer, Sansui, Marantz, and other brand receivers and amplifiers will develop transistor issues over the years, and these brand new Fairchild/OnSemi KSA1381ESTUs are a great way to fix that. I personally use these in receiver rebuilds, and go through quite a few every month.

US shipping and handling is $7, and international is $21, no matter what quantity you buy. All of my small parts are set up for combined shipping--just use the "add to cart" feature and then check out at once, and the shipping will be automatically discounted.
