Hi all.
I am new to this forum and I have what I guess must be a pretty simple problem to start with.
I would like to make a guitar amplifier for my A2 level Product design project and so I thought I would start with a simple transistor amplifier to get things going. Basically, I have tried this a few times and watched videos, read books and seen schematics and I cannot get this circuit to work (see attachment for schematic).
I can hear the interference when I hook up the battery so it all must be connected up, right? But when I plug the guitar in, I get no sound out of the speaker whatsoever. I have tried to follow a schematic I saw on youtube for a transistor preamp where his input was a mic and his output a PA speaker, he ran it through an IC power amp stage though. Do I need to do this to get any sound?
If I need a power amp stage then I would prefer to make it myself out of transistors instead of an IC as I would like understand how it all works, so does anyone have a schematic for a basic power amp stage?
Any help would be appreciated as I don't really know where I am going wrong.
Thanks in advance
Callum
PS, the transistor is a 2N3904 if this matters
