it woun't have clarity as tl074/84
your saying about clarity...its way beyond dude....i get a huge short accros the series....when i connect fets dont know why...can u plz help me out
Nonsense, it wouldnt work at all.it woun't have clarity as tl074/84
Look at the slew rates:
lm324: 0.4V/us
tl074: 15V/us
Lm wouldnt oscilate.

If you are using lm's? Thats probably the reason your fets are smoking.

gr8 thanks buddy.....but are u definite with ur opinion....and what would be the other reason if this aint be the prob
hi guys. the hi power version in bridge mode. i will upload artwork later

Stewin, you sure love what you do! Great work!hi guys. the hi power version in bridge mode. i will upload artwork later

i thank GOD for his help . long time welcome back.
hi all i made bridged version and tested it but . when i pushed it hard with a 6ohm load that is a 18inch woofer the amp failed after 2 minitues. .i think my tracks for pcb were small the ones feeding the output fets. also

Use resistive load for testing...don't you care about your speakers and your ears?.
Also any amplifier must survive continuous rms power into resistive load to be reliable with music.
resistive loads like ? resistors in parallel to match impedance desired?
sweetperfume:
No,the opposite is correct.
A speaker is a non resistive load, in fact it is a nonliniar inductive/capacitive/resistive system depending on its configuration(single or multiple in cabinet and with or without filters).
stewin:
Power resistors with their resistance smaller than rated impedance, example: for 4 ohm impedance use 3 or even better 2.5 ohm low inductance resistors or resistor network

hi all just found this schema by detex audio . it seems simple . what makes it 100watts and not 200 watts?
