Remember when they used to be ECG. I can’t even find a datasheet for 2SC on the web. The finals, though, is not where he allegedly has the problem. Shorted outputs, shorted drivers and pre drivers.
Were the replacements matched? Anon6f72b to Anonb Anon Jun-7 2: Personally, I’d tend to think datasheef the chances of getting genuine parts from Digikey is pretty good. And, if they’re made of unobtainium, yes, good luck. Then again, this was around 10 years ago and earlier. Perhaps things have changed, but, when I used to use NTE substitutes, I never had a bad one out off the box and datasheef of them failed after being installed.
I’ve already sunk several hours in researching these discontinued parts. Octopart says no datasheet found and they ask to submit a quote request. Anon6f72b Anon Jun-8 3: They were “ok”, but very datashert when compared to the real thing.
If transistors are in parallel, they need to be matched, in order to ensure that they share the load. I managed to get 32 datashewt that matched to my tolerance. Anon6f72b to Anonb Anon Jun-7 3: I think it ran right at the limit of current.
I’ve seen that with 6.

The substitute parts have a higher Ic, as well. Comes up not found at my regular suppliers.
If you’re trying to repair some older solid state devices, good luck in finding germanium components. 2ss968 of which give me a whole lot of peace of mind though. NTE has a horrid reputation among repair circles and I like to avoid it.
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?
Anonb Anon Jun-8 There is evidence that the Darlington pairs had been replaced with substitutes fresh solder, part numbers differ from schema. I think the op simply wants the exact same components.

Due dtasheet 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. Anonb Anon Jun-6 9: A little too close for comfort on the spec.
Dear Comcast, I won’t use your email service Also the MV diodes get replaced, as these are notorious for failing and turning on both halves of the output stage simultaneously. Obviously, certain critical parameters have to be met, but even then, operating something close the edge could still lead to early failures. Repairing a Sansui G The risk of having one fail and take out a half dozen expensive output transistors, plus devices on the driver board, seems too risky.
One circuit I worked on used to use an MJ It’s like that feeling when you step into a mud puddle and discover it is much deeper than it looked 22sa968 you find yourself up to your knees in mud and think “well, I may as well keep going.
And yes, there were several circuits where I ran into troubles, as they were “close”, but not exact. Anonb to daveinpoway Anon Jun-8 3: This may have been part of the reason the recent repair using substitutes failed. They really ARE made of unobtainium! Would typically last a year.
