2SA968 Datasheet

Anon6f72b to Anonb Anon Jun-7 2: Of course transistors have many more crucial parameters than caps, and sometimes one has to compromise when the original part is made of unobtainium. That was troublesome even 30 years ago! NTE has a horrid reputation among repair circles and I like to avoid it. If not, this could be a reason why the original repair only lasted a month.

They were “ok”, but very expensive when compared to the real thing. I don’t share that opinion.

Repairing a Sansui G Anon6f72b to Anonb Anon Jun-7 3: I think the op simply wants the exact same components. And, if they’re made of unobtainium, yes, good luck. There is evidence that the Darlington pairs had been replaced with substitutes fresh solder, part numbers differ from schema.

Datasheer Anon Jun-8 3: Were the replacements matched? Anonb to daveinpoway Anon Jun-8 3: Personally, I’d tend to think that the chances of getting genuine parts from Digikey is pretty good.

Widespread Centurylink Outage this morning I can’t even find a datasheet for 2SC on the web. Anonb Anon Jun-7 5: I managed to get 32 devices that matched to my tolerance.

Something in the back of my mind tells me I should have firmly satasheet down this job. In audio applications, the fT won’t make a difference. The finals, though, is not where he allegedly has the problem. My biggest concern is having the amplifier come back a month later because the parts didn’t last. The originals are 25W dissipation, while the substitutes are 20W dissipation.

I think it ran right at the limit of current. This may have been part of the reason the recent repair using substitutes failed.

If transistors are in parallel, they need to be matched, in order to ensure that they share the load. Friend bragging about 10 year old car with really low mileag [ Automotive ] by IowaCowboy Class A is the most inefficient, dafasheet yes, the constant power dissipation will shorten the life, especially if the substitute has a lower Pd.

Forward current transfer ratio hFEmin: All of these parts are shorted, so someone attempted repair using substitute parts and the parts failed again. One circuit I worked on used to use an MJ Also the MV diodes get replaced, as these are notorious for failing catasheet turning on both halves of the output stage simultaneously.

Supposedly have many of each in stock, and cheap. Anonb Anon Jun-7 The pre drivers, 2SC and 2SA are proving to be even more elusive than the drivers! I’ve seen that with 6. It was not that they were bad, it is that thay are a 2sa9688 replacement for many parts. Parts Express has the NTE parts. You mean re-marked so it’s not what it’s supposed toor just a fake datazheet, so a possibly inferior product can command a higher price?
