Hi ,I just build my lme49810 project.And after measuring power looks I am mess up.Power is Ok in 40Hz and 100Hz,but only about 100W in 500Hz and up.Any ideas were to look for my mistakes?Thank you.
Power is OK at low frequencies?
But at medium and high frequencies the output power decreases?
Interesting...
What schematic did you use?

Thank you for respond.I am using this schematic.

If you can't open this link let me know.
Actually I found in my board wrong capacitor C13,by pin#6 of lme49810.Should be 10pF,but I put 10nF.I didn't have time to put right one and check it.This weekend I will have time to show you my wave forms input and output with different frequency.

Zolux. Any progress?
Are you sure you have the C/E connected the right way on your output transistors?
If not that, I can not think anything else than a short on your PCB somewhere...
