Re: Logitech X-230 amplifier - upgrade possibilities?

hello guys, i ordered through a business email of a friend samles of lme49740na and lme49860na and they denied, saying that they cannot process my order and i should be adressed to national in germany! do you have any idea what to do?

Rather odd as you live in Greece that they told to do business with National in Germany... Could you paste the e-mail or the critical parts of it?

And also, what do you mean with this:

i also changed the np's into the satelites

You changed some components, but what exactly? NP doesn't ring any bell for me. Thanks!

Hi to All,
I have Philips SPA9300 2.1 system. I decided to change the Op amps inside. There were 2 JRC4558D. In my opinion these amps are for active filters. I changed them with OPA2132P. Maybe there is an improvement or I presume.

The best way is to solder 8DIP sockets in order to try different amps .
