Hello, everyone! thanks for the replys
Here are some pictures. I have 3 speakers of this kind and they all have the same type of coil and magnet. The screw in the back acts as a On/off switch I would say. You screw it and it makes contact and you can hear the speaker work.
Sorry for the messy...
Hello everyone!
(I apoligize in advance if I ask noobie quiestions, but I'm a beginer in this matter)
I have a 1920s vintage speaker that is in a pristine condition! I intent to use this speaker with a small powered guitar amp that I've built. The guitar amp is called "ruby" wich is a 9v...
Hi Brian, thanks for the reply. I picked up the wiring from here: https://www.instructables.com/Creating-An-Audio-Reactive-LED-Circuit/
It all goes to the same battery that feeds all the circuits, the tremolo, the amp, and the added LED with the transistor. I figure what you said is correct...
Hi everyone! hope you are good!
I have a question. I've built this tremolo effect guitar pedal and I was thinking ono addin and LED that reacts to the tremolo signal (blinking on and off). Now, the thing is that I linked the circuit to a guitar amplifier, so it's like a built in guitar amp with...
Hello everyone!
I have this guitar amplifier that I've added a tremolo circuit. I manage to add a DPDT switch to select between the clean signal (goes straight to the amp circuit) or the tremolo circuit (goes to the tremolo and then to the amp)
So, there is a way of replacing the DPDT switch...
I was only trying for fun. The fun thing of these proyects is to see whay a speakerphone sounds like with a guitar. Sometimes you get fantastic results, sometimes not (this seems to be one of them) but its a matter of taste. Some people like hifi supler clear stuff, some others like the sound of...
But this speaker is 2W and 8ohm, so I don't quite understand why its not working good enough if the amp delivers 0.5W at its max...or 2W is an estimate number and the real one is lower?
Ok, I'd put FIVE! 1M resistors in series and, it work just a little, but still, the rattleing continues altough a quite less. I guess that I should try another speaker bucause this one doesn't deliver the goods. Do you guys have another alternative?
Thanks!
It is the speaker. I've built 4 of these amps with the same telephone speaker and the problem is exactly the same, also I've built a ruby amp with a propper guitar amp speaker and works perfect. Maybe if I increase the resistance of the small telephone speaker by adding a resistor, but with 8...
Hello everyone! its me again! Well, I must tell you, I've been practicing and I've built a few of these ruby amps and I'm learning quite a few things!
I'm using an 1980s telephone that comes with a built in speaker that was used as a speaker phone. The problem is that it distorts and rattles...
actually I purchased a 10W kit aswell and put it together. On its own it sound veeery low volume, but when you use pedals with it, it rips. I don't understand why that happens.
Hi! The Full Fat is a kit that I bought a few months ago. The problem with that one was that the volume pot (470 ohm) behave strangely. As you start to turn the volume up the signal was really low volume, then in the last quarter turn the volume steep up exponentially. I talked to the seller and...
Hi Brian, yes, I had the wires the wrong way around. Now its working propperly. I've been reading that, to get more power I should try different Op amp chips. Thank you for the advice on the LED resistor, I'll change it to get more battery life.
Cheers!
Hello! Yes, I tried with a 6 ohm speaker and no sound came out of it. Maybe I need to wire something differente for it to work out.
I'll look up about different chips, and if I need more powerfull power supply.
