Default LM4780 from who?

Hei!

I desided to builed me the Lm4780 chipamp (dobbel mono).

And now the question:

Who's construction/designe is better, who sounds better (not inn therory), chipamp or audiosector?

I know the the only difrents is the zobel, but I ask anyway



Hilsen

Jarre,

The design is essentially the same. I haven't stocked the LM4780 boards for a long time on, and Peter should have them available for ordering now. Peter took the board for one more revision, adding the ability to run both channels seperately to allow for a stereo amp to be build from one chip.

Best of luck on your project,

Then the case is closed, it will be audiosetor.

A noter question, withs 10 000uF capasitors are recomended. Because the Panasonic FC does not go so high

Thanks for the advice BrianGT!

But I have resacrted today and found Mundorf caps for amplifilers inn Norway.

Do's someone have any expirens whit Mundorf caps for amplifilers?

They are more exspensiv (Panasonic aroud 50 Nok (8,2 USD), Mundorf 130 Nok (21,3USD) for the 10 000uF), but I thout it will be more exspensiv. I think I will try them. Then I have too save some extra weeks
