Thanks for replies gyus/girls
Yes, it needs to be cheap, because it will be used outdoors, sometimes in rain (i doesn't be so bad thing then if it breaks or gets stolen if it's cheap). I also need lot's on desibels - it will be played in area bigger than 200mx300m and it would be nice if it can be heard anywhere, thats why lot's channles and power. Sound quality is not so important as said, just to get music play.

In home i have "hi-fi"-gear, GainClone, and for headphones Meier natural crossfeed amp and Szekeres fet follower, but we don't need that much hifi-systemin track.

Class-D amp surely could be good option in this application.

Thanks for everyone again

Hi Big!

I don't think that you can bridge this amp.
The center tapped output windings in push/pull configuration
already perform a similar thing like a bridge...

Unhappy I do not know

I suppose may have some way....separating audio phase and input them separately into two units.....but output has DC voltage.....you will have to put at least big capacitors.....I really do not know how to make it.

But we have people in our forum that can give solution to almost everything.... and they also have knowledge to say something alike... forget it.... i cannot say that because knowledge is low... this way a lot of doubts happens in may mind..... maybe interconnecting low wire from the first amp, throught a big condenser to the hi position output of the second one.... and using the other two output wires as a new output using condenser too...... i do not know...maybe they will cancell the audio because of phase.....maybe not.

the reason i am entering here is some responsability because i put that schematic in our forum... and i feel afraid to create you some problem...or other friends troubles.

Carlos ....Destroyer X.....an old man (52), but new in forum and never studied electronics in some school....just burning fingers and reading magazines.... i am a Psychologist in degree and a TV broadcasting professional in the Technical area of maintenance , related to repair some fast problems, substitute fast burned machines, calibration in step by step manual procedure and equipment operation.

I am here to learn audio.
