I'm enjoying this series on the LM386 opamps. Got some myself and am experimenting to see what sounds best. Definitely going to try this out. One thing I'd love to see in your future videos if possible is if you could put a circuit diagram alongside your footage. Would be really helpful for showing exactly what you're putting together so people like me could replicate your experiments more easily.

@Max-pc8qz 4 ай бұрын

Those diodes are wired in coring arrangement and not a clipping arrangement, so you're actually cutting out the middle of the waveform with those diodes.

I neeed there to be a forum or Reddit on stuff like this. I got a Marshall MG50DFX and I need to modify it. The overdrive channel the gain comes on way to fast, but then never gets high-gain enough. And for the clean channel there is a “gain level” but it’s pretty much a volume knob, at 10 it’s just louder it, it doesn’t break up at all! I am going to mess with the resistors and clipping diodes on the overdrive channel but I’m not sure what to do with the clean channel. I am interested it making this a usable amp, I’ve though about adding a tube preamp and a EQ and building a box for it for it to be a little head.

@zurowetz 2 ай бұрын

Be careful messing around in a amp if you don't know what you're doing sounds like maybe you need a new pot for the overdrive gain remember that if you change the diodes in the clipping part ( if the amp uses diodes for cipping) the volume of the amp will change and so turn down the volume and slowly bring it back up so you don't blow the speaker/ your ear 🙂

Try diodes on both outputs 1n4148 on second output and small and large LEDs on first output as a boost into the second stage and adjust the gains to create an interesting sound I'm sure. Perhaps add a sweep tone or tone stack

Great that you made the box😀👍sorry to hear that you are having problems with the lm386 sounds like you are using too much power it's 5-12 volts and dc so make sure you are using the right power also it can be the impedance have you tried with a battery?

why are you not clipping to ground thats they way its normally done all tho i know it can be done how you have it hooked up too its just not common. you would need a dc blocking cap before the diodes to stop DC getting into the opamp
