does anyone know where i can find A968A (2SA968A) complementary pair C2238A (2SC2238A) or suitable subs?
Sorry, I dont see a complementary pair. Maybe someone else in the community has a suggestion.
Many of the older 2S( ) devices have faded into obsolescence/obscurity as a result of changing design practices. When demand fades, supplies dry up. 'Aint many folks making new-production CRT displays these days either…
Going to the Single Bipolar Transistors family, filtering for package and Vce and looking for something at least vaguely similar on the remaining points is the straightforward route. What exactly might constitute a “suitable substitute” is somewhat application dependent, and it’s up to you to decide what is or isn’t.
On that note, 2SA1668/2SC4382 are a pair that’s available and of potential interest.
