[Manekinen]

Shit, dude, read! It is 2x150 + 75, and that is 375W! Radiators and 450W transformer inside! You still think its too big?

Widziałem temat na elektrodzie. Świetna robota ;) Pogratulować :) Fajny głęboki bas...

you do know its bad to max out amps you retard

AMPLIFIER IS NOT OVERDRIVEN, but microphone in camera clipping. Try to record something like that at 1m distance!

I`ve made a couple of videos of my amp u can hear the buzzing on the second video . :) I`d like to hear some suggestions . I think I did not use the correct type of wire for the audio cables . Or the transformer is to close to the integrated circuit . I`m using 2 enormous capacitors i don`t realy remember the farad reading on them , all that I know is when I accidentali touched with the screw driver the positive and negative ends the screw driver melted and the bolts ... so i think they are ok .

Hello nice job the amp is extremely good looking and poverful. I see u`r using TDA7294 , on what voltage are you using it ? I`m building right now an amplifer which has 4 TDA7294 , and in my documentation it seas that it has 2x250W , but on 40V and (max) 10A . But I am using it on 30V adn like 5 A ... . I have a question mine has a Stand-By function I have to give it 5V to get it auto of stand by ... but I don`t know if it needs it permanently or not ? And i have a terrible buzzing sound ...

@Manekinen relax yourself there blowjob im srry i read it to quick and yes i still think its big..theres amps out there that are single space that,that's 1/4 of the size and it puts out 8500 watts

@Chris25toepher Class AB amplifiers are larger due to the lower efficiency, which requires a bigger transformer, capacitors, and heat sinks. Especially the heat sinks in a passively (fanless) cooled amplifier, they need to be considerably larger.

I built an amp that is about the same size as this and puts out 400Wx2 but it is class D, which can pack a lot more punch in a much smaller package :)
