Up for sale here is this set of 10 (ten) brand new Onsemi KSA1013YTA transistors and 10 (ten) brand new Onsemi KSC2383YTA 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 are usually found in complementary pairs, and here you can get 10 of each, making your repair work easy. Many vintage Pioneer, Sansui, Marantz, and other brand receivers and amplifiers will develop faint crackling in one or both channels as a result of small transistors going bad, and these brand new transistors are a great way to fix that. I use these exact transistors when I restore gear--they're fantastic!
The "YTA" suffix means they are the "Y" hfe classification and are attached to paper TApe.
Please note that these are marked "JCC2383Y" and "JCA1013Y" in very tiny print--that's how Onsemi marks them now.
