Why i always have those losses in power using lower impedance loads?

[richie00boy]

SPICE models can be accurate, but it depends on the model and it's complexity/completeness. Not all models are good.

Thanks for your kind words Carlos.

Hi,

True. But the point is accurate SPICE predicts these losses.

Now i have my old 5 neuroniuns working harmonically.... all them slowly processing data.

He informed that this saturating voltage losses can be compensated using 4 output pairs.

Also introducing the needed current, into the drivers and output...from the VAS that current.

So...a matter of a good supply, a good design, enougth currents and good output pairs and the lost will be smaller...of course emitter and some losses will be accepted, as finally i know the reasons and this loss do not surprises me anymore.

I am extremelly satisfied with all folks contribution, informations and kind assistance.

Carlos
