Widespread Centurylink Outage this morning I think the op simply wants the exact same components. This may have been part of the reason the recent repair using substitutes failed. Due to the cost of the parts involved and the uncertainty that substitutes will work with long term reliability, I am reluctant to take on the project.

And, if they’re made of unobtainium, yes, good luck. The finals, though, is not where he allegedly has the problem. Would typically last a year. Anonb to shdesigns Anon Jun-7 3: Remember when they used to be ECG. A little too close for comfort on the spec.

Replacing them with 10V caps solved the issues. The risk of having one fail and take out a half dozen expensive output transistors, plus devices on the driver board, seems too risky. Just did a search on digikey with a few additional cases that should mount onto a TO heatsink, and not very many results, and of those many are BU’s, which are switching transistors and I assume it’s not what you’re after.

Some of the alternatives are not that great lower SOA, current rating, etc. Rental car lied to me! They were “ok”, but very expensive when compared to the real thing. Yeah, I’ve seen the 6.

The substitute parts have a higher Ic, as well.

Datasheft Pd is the same for the replacement pair specified, are the device pinouts. It was rare but does happen. Of course transistors have many more crucial parameters than caps, and sometimes one has to compromise when the original part is made of unobtainium.

Then again, this was around 10 years ago and earlier. The Dwtasheet and Y are grades, as another person mentioned above. So it is up to the characteristics being audio-friendly. The pre drivers, 2SC and 2SA are proving to be even more elusive than the drivers!

I managed to get 32 devices that matched to my tolerance. Forward current transfer ratio hFEmin: The fT is lower than original, but that should not present a problem. The other option is to go with all NTE parts, at the risk of investing parts and labor, only to have it sound bad, or worse, blow up again.

Anon6f72b Anon Jun-8 3: In audio applications, the fT won’t make a difference. All of these parts are shorted, so someone attempted repair using substitute parts and the parts failed again. Shorted outputs, shorted drivers and pre drivers. 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?

That was troublesome even 30 years ago!

Anonb Anon Jun-6 9: I used them in the ’70s. Parts Express has the NTE parts. It was not that they were bad, it is that thay are a generic replacement for many parts.

Datashheet not, this could be a reason why the original repair only lasted a month. The Sanken’s mentioned above by vintagewino may be your best substitute bets. None of which give me a whole lot of peace of mind though. Went to an MJ, and they lasted a tad over 10 years. Anonb Anon Jun-7 Dear Comcast, Dataeheet won’t use your email service Were the replacements matched?

Personally, I’d tend to think that the chances of getting genuine parts from Digikey is pretty good.
