It would be interesting to study how these kinds of issues impact engineering and manufacturing practice throughout the world. In the U.S. it's been far too easy to take supply chain stability for granted. It's a privileged position to be in that comes with potential danger unless you maintain some strategic know-how for when circumstances change.

Just a question... was the 3886 ever used in series produced mass market amplifiers, and if so, up to which year, and by which maker?
Mass market means a large scale operation, having at least 5% of the overall market in total of all models.
Not some small workshop operation.

Probably not much in dedicated amplifiers, but they’re in powered monitors and TVs everywhere.

Those are serious markets, more important than our smallish Audio/HiFi.

They have also been reasonably popular with Musical Instrument amplifiers.
Line 6 , Behringer, Peavey, Tech 21, come to mind, also as horn drivers in tons of biamped cabinets.

The common theme here is that al these devices have built in speakers. There are a *lot* of them.

Thanks, I just wanted to know if they were used at all in mass production items.
Your answers are yes, they did.
So TI might bring it back.
Or some adventurous person can try the copied ones for quality.

Nice catch, hadnīt realized that but of course itīs true.

Personally quite the functionalist, so Iīd be happy with anybody offering me a "black box", in this case a small black plastic rectangle with 11 pins, couldnīt care less about WHO makes it, even if internal circuit (which I donīt see) is the same or different, as long as reliably meets the specs, can be sourced in quantity and ... ahem!!! .... costs less.

Weīve already talked about my preference of Indian made UR/USHA 2N3055H transistors which I preferred over "official" ON/Motorola or ST ones, go figure, because they met and surpassed my qualifications above.

PRAY
some "USHA" out there manufactures drop-in LM3886 substitutes, even if TI restarts production, just for peace of mind.

Hate being tied to a single supplier.

I have seen Alesis amp modules with LM3886, probably not with 5% market share!

I’m pretty sure I’ve seen it in Cambridge Audio integrated amps of the last ten years , one per channel, and one usually has a hole in it

What’s the matter, MJ15003s just cost too much?
