60 w power amplifier

[meledath]

Dear friends,

i want to construct a highly stable , very low distortion audio power amplifier for household use in 60 to 100w range. Where i can get the circuit?

Please help

You could try Rod Elliot's 60-100W power amp.

PCBs are available for it, too.

THANKS FOR THE COMMENTS,

IS ANY OTHER CIRCUITS USING MOSFETS AVAILABLE ? SHOULD BE REALY WORKING AND HIGHLY STABLE.

How about Project 101?

Thanks ,
do any one have working schematics which use op-amp as input stage and mosfet o/p stage having highly stablility and ultra low distortion.

All are welcome to this discussion

opamp and ultra low may make a poor sounding audio amplifier.
If done correctly it may make an exemplary amplifier based on conventional measurements.

THANKS ,

Waiting for comments from all experienced people.

;;;;;I DO REALY NEED A WORKING CIRCUIT. I AM AFRAID OF THE DESIGNS IN ELEKTOR. MOST OF THEM FAILS AFTER ASSEMBLING;;;;;;.

You can always hack together a Musical Fidelity B200.

Or,if you think you're up for it, build a YAP : YAP power amp revisited, now at v2.1

HE HE HE TRUE .... but realy .... is any of the elektor amplifier ever worked properly ????

i think not ... meaning that most of their amplifiers was stragles to introduce this or that technolgy but sound results were always strange ...the amplifier had this but not that and the model who that didnt had this ... and all of them together never had one of the most importand : stability under all cases ...under some cases yes under all cases ....or if all is too much let me say most then ....

(I am alwoed to have my personal opinion in this ..... )

in real life

in the forum one of the most popular at this range of power and plenty of support is two ( the DX amplifier and the esp P3A amplifier )

to my opinion the DX amplifier is very honnest accurate stable and also measures properly

to my opinion the P3A amplifier is more musical less accurate and more nervous than the dx ( bennefits of sziklai ) also stable and doesnt measure that good next to the DX

you may choose what fits you better

though you need to keep in mind that terms like low distortion dont come from a schematic .... construction, pcb, wiring , psu and the total layout makes a hell of a lot of diference to achive a target like that

happy regards sakis
