If you do not need the full power you could use the TDA2030 instead.

Do you need a single IC, hundreds, or thousands? If you need just one to fix a guitar amp:

STmicro no longer makes the TDA2050. I checked usual distributors (Digikey, Mouser, Newark, Allied, etc) and nothing found. No obvious plugin substitute either.

Jeff, perhaps you don't know about findchips or octopart. (I'm starting to like octopart a bit more... much easier to compare prices.)

I don't need full power.. would it 'drop in' ? I need a few hundred

Octopart also shows datasheets when available, often from different manufacturers.

If they are missing one, and you happen to have it, you can upload it easily.

They are very easy to deal with if you have a problem. I reported a bug a while ago and they sent me an Octopart T-Shirt. Fits perfectly.

Grin, an octopart tee shirt is surely geek wearing apparel.

As far as I read the datasheet it will. Only the maximum value differ in that the TDA2050 is specified for +/- 25V supply whereas the TDA2030 only has +/- 22V for maximum supply voltage.

I know about them, but have been too lazy to use them. Instead, I use a local web page, which I scribbled years ago, that plugs the part number into the various distributors search URL's. Something like these, where the tda2050 part number is passed from a search box: etc. Time to get rid of my method and use something better. Thanks.

There are 53 people selling them on E-bay.

I vaguely remember having seen a TDA2040 in a cheap guitar amplifier, so such thing would appear to exist.
