The fT is lower than original, but that should not present a problem.
Rental car lied to me! NTE has a horrid reputation among repair circles and I like to avoid it. Anonb Anon Jun-6 9: Anon6f72b to Anonb Anon Jun-7 1: Then again, this was around 10 datasbeet ago and earlier.
If you’re trying to repair some older solid state devices, good luck in finding germanium components. So it is up to the characteristics being audio-friendly.
Toshiba 2SA Datasheet.
The substitute parts have a higher 2ssa968, as well. The risk of having one fail and take out a half dozen expensive output transistors, plus devices on the driver board, seems too risky.
Some of the alternatives are not that great lower SOA, current rating, etc. Parts Express has the NTE parts. It’s rare to find any Sankens that are NOT counterfeit parts these days.
Every rebuild of this magnitude comes with a mandatory recap. This may have been part of the reason the recent repair using adtasheet failed. That was troublesome even 30 years ago! Of course transistors have many more crucial parameters than caps, and sometimes one has to compromise when the original part is made of unobtainium.

It’s like that feeling when you step into a mud puddle and discover it is much deeper than it looked and you find yourself up to your knees in mud and think “well, I may as well keep going. I’ve seen that with 6. Class A amps were one case.
Yeah, I’ve seen the 6. You mean re-marked so it’s not what it’s supposed toor just a fake manufacturer, so a possibly inferior product can command a higher price?
Anon6f72b to Anonb Anon Jun-7 2: There are people that argue that matching isn’t critical if emitter resistors are employed. Anonb Anon Jun-7 5: The output transistors appear to be original Sanken RETs. Friend bragging about 10 year old car with really low mileag [ Automotive ] by IowaCowboy Most Active Forum Topics this week Octopart says no datasheet found and they ask to submit a quote request.
The O and Y are grades, as another person mentioned above. I’ve already sunk several hours in researching these discontinued parts. It was not that they were bad, it is that thay are a generic replacement for many parts.

I purchased transistors from Mouser and spend an hour grading and marking them all. Dear Comcast, I won’t use your email service Widespread Centurylink Outage this morning I’m not comfortable with this situation, but he’s a regular customer and I don’t want any bad blood for refusing to work with him on this one. I told him it’s not worth more than a grand in non-working condition, but he was unable to negotiate cheaper 2sw968 badly wants this receiver.
