Hi , i dreamt of a good poer amp for long and found circuit that tells
I hv assembled it .however after running the power amp with some inputs i was surprized to see that the AMP is very weak .. it needed 15a-0-15a supply ..that cosed 20% more
whole amp kit costed 40% more ...finally I to discover that it is v poor as compared to kits with 4440 ICs ..
Is STK 361 weaker IC as power amp than LA 4440 ,please coment ..
do you have a power supply that can provide at least 720 W? Class AB amplifiers are only 50% efficient or so, so you'll need to provide double the juice it needs from your power supply.
thanks ,
360 w PMPO that was the title of the circuit published in 'Electronics for you ' magazine ...STK 361 is some 25 or 50w rms chip i think .. Is the power supply that might be the cause ?? the Amp was running fine ...amplifying but But very poor Output.....(i hope a power supply *stronger* than normal PSs of 12-0-12 3 Amp LA LA4440 based amps should be sufficient ])
Dears I think you should try on KIA6216H ICs, May be it gives you better result .
