2SK369 (matched pair) is not really a direct replacement for 2SK389. It has about twice the transconductance and twice the capacitance. 2SK170 is a better substitute. There are still plenty of sources for both. And if you look hard enough, you can still find 2SK389, at a price. 2SJ109 is a different story .....

B&D Electronics has original parts for most Japanese transistors. I've been
buying from them for 15 years or so. Excellent source.
I hope they're stock does not become depleted now that I let the cat out of the bag.
