KSA 1220

[Nelson W]

Hello, all good people
Could you please advise me on what other transistor I could use, given that the KSA1220 transistor is currently—as of late 2026—unavailable for purchase from distributors such as Mouser or DigiKey?

I would need it—the power amp Pioneer SA 9800 GWH PCB Q7 + Q8 2SA912 ,and for the power amp Pioneer SX 737 AWH033 Q9 + Q10 2SB527 as well.

I, like others, will certainly appreciate your advice.
Thanks.

Nelson.

I'm guessing Affinity for artifacts on eBay would have some. They'll be genuine, he's a known member here on AK.

Thank you for the quick, well-intentioned advice. However, I am in Europe, and the ones I found here on eBay are from China—so I don’t know what their quality is like or whether they are worth buying.
