Replacing them with 10V caps solved the issues.
2SA968 Datasheet, Equivalent, Cross Reference Search
Personally, I’d tend to think that the chances of getting genuine parts from Digikey is pretty good. Anonb Anon Jun-8 This may have been part of the reason the recent repair using substitutes failed. Then again, this was around 10 years ago dataeheet earlier.
A little too close for comfort on the spec.

Yeah, I’ve seen the fatasheet. None of which give me a whole lot of peace of mind though. I’ve seen that with 6. That was troublesome even 30 years ago! Dear Comcast, I won’t use your email service I 22sa968 transistors from Mouser and spend an hour grading and marking them all.
Remember when they used to be ECG. It’s like that feeling when you step into a mud puddle and discover it is much deeper than it looked 2ssa968 you find yourself up to your knees in mud and think “well, I may as well keep going.
Octopart says no datasheet found and they ask to submit a quote request. All of these parts are shorted, so someone attempted repair using substitute parts and the parts failed again. Forward current transfer ratio hFEmin: Whether they will work satisfactorily ddatasheet this circuit remains to be seen.
The fT is lower than original, but that should not present a problem. Anonb to shdesigns Anon Jun-7 3: Anonb Anon Jun-7 5: The finals, though, is not where he allegedly has the problem.
The originals are 25W dissipation, while the substitutes are 20W dissipation. Class A amps were one case.
But yes, the hFE should be close for each group. Most Active Forum Topics this week I think it ran right at the limit vatasheet current.
Friend bragging about 10 year old car with really low mileag [ Automotive ] by IowaCowboy They were “ok”, but very expensive when compared to the real thing. If you’re trying to repair some older solid state devices, good luck in finding germanium components.
Anonb Anon Jun-7 Repairing a Sansui G I used them in the ’70s. It was not that they were bad, it is that thay are a generic replacement for many parts. The pre drivers, 2SC and 2SA are proving to be even more elusive than the drivers!

Anon6f72b to Anonb Anon Jun-7 3: NTE has a horrid reputation among repair circles and I like to avoid it. Class A is the most inefficient, so yes, the constant power dissipation will shorten the life, especially if the substitute has a lower Pd.
Also the MV diodes get replaced, as these are notorious for failing and turning on both halves of the output stage simultaneously. Of course transistors have many more crucial parameters than caps, and sometimes one has to compromise when datashfet original part is made of unobtainium. Anon6f72b to Anonb Anon Jun-7 2: The Pd is the same for the replacement pair specified, are the device dataxheet.
Supposedly have many of each in stock, and cheap.
I think the op simply wants the exact same components.
