TDA2050 max single supply voltage?

[Signaling]

Thanks for the help everyone! I guess now I should go and actually build something, I'll try a base gain of 30 and make it adjustable to 50 using a small trimmer to find the right balance between volume and hiss.

No idea why failed, could be overstress, manufacturing fault.......
Remember these were intended for domestic amplifier use, it's just that Guitar Amp designers saw a low cost opportunity to put into their cheaply made in China etc. products & sell at inflated prices to Yoof who wander into Music stores having seen Vox & Marshall logos on Top of the Pops 😀

Many years ago when I was a service tech and we used to replace TDA2030's (no TDA2050's back then) by the bucket load. They were used in all sorts of cheapo audio systems and certain horrible TV/Audio tower combinations. Somehow the customers managed to get them to go up in smoke.

It makes you wonder how loud do some people have their audio systems cranked up to, I never get anywhere near the half way point on mine before it becomes too loud for my liking.

Then again consumer electronics is about doing everything they can to reduce cost whilst keeping the marketing department satisfied.

You might be surprised 🙂

Speakers placed on open windowledges in flats, all blasting out trying to out do each other.

If you feel that total supply voltage is your bottleneck, you might consider
utilizing LM1875, which is pin compatible, still being manufactured and a
60 V component.
