@siwy125552 I guess it could run on 30 volts, but i wouldn't try anything more than 24, somewhere between 15 and 20 volts should be ideal for this amp, I ran this on about 12v in this video if I remember.
@siwy125552 Should be somewhere between 5 & 8 watts but I couldn't get much out of it. However if you want to build some powerfull amps, check out destroyersoueu's channel, he has designed many amplifiers, and has scematics and other usefull info as well youtube.com/user/destroyersoueu . I built one and it sounds great.
if i make a low pass filter with a 1nF cap and a 10K resistor, i have calculated that the limit frequency is about 16kHz. is this enough? if not, what would be a good limit frequency so i wont have any radio interference from power lines and such in my guitar effect
Hey I know this is kinda random but I'm building a distortion effect for my guitar and it uses the LM308 op amp and for some reason I have a lot of crackliness and I even pick up radio stations on it sometimes. I'm guessing that I need to change the high and low pass filters but if I'm wrong please tell me
@MrDixiepride1234 If it's picking up radio stations putting a capacitor across the input jack should help fix that, try 1nf at first, if it muffles the sound go lower, if it doesn't fix the problem and doesn't muffle the sound too much try a higher cap.
@CoolDudeClem well if i put a 1nF cap with a 10K resitor to make a low pass filter, i have calculated that it would give me a limit frequency of about 16kHz. is this good enough. if not, what would be a good limit frequency that way i wouldnt have any interference from the power lines and other electronics.
hi if yore yore cerkit is perfect u have to chek ! 12 volt battry if is perfect work u have to use 4007 diod brig 4700mfd & 7812 regulater for exectly pure12volt dc my e mail adress is faris_123@live.com byy
@racetest Any diode from 1n4001 to 1n4007 should work fine, the original diodes I used here in the video were not exactly the right ones to use and it did take more power than it should, but sometime after I made this video I tried it with 1n4001 diodes and it ran much better and cooler. I even tried it with a single yellow LED in place of the diodes and that worked just as well.
I have an old pair of amplified USB powered computer speakers with a busted volume knob but the pot is still there and still works. I might drill a hole in the broken pot shaft and then insert and superglue a long skinny screw to it.
@jorge1320e do you have a volt meter? if so test the voltage at the speaker connection and adjust the potentiometer untill the voltage there is half of the power supply voltage, that should fix the problem.
Nice to see that. I juz wana ask about my problem w/ my ampl. speakers, it just reverberates when i turn on its power, even when i disconected EVERYTHING from it, except the power cord, of course. Help me please?
i got 4 x 2n3773 will they do for a amp ?

@TheOffPowerZero as long as they are used for the final two output transistors it should work.
