Hi, I'm planning on building a guitar amplifier, but have some doubts about what to use.
I'm not really interested in some big high power amplifier, but something simple and small/light.
The basic blocks I'm thinking are :
- initial signal conditioning (I think this is how its called) :
I've been said to use a differencial pair, but I think an op-amp would work fine too right? Or is there advantages to using with discrete transistors?
What kind of circuit would be preferable?
- effects :
this I'm more at ease, still not sure what I'll do, but at least a distortion effect.
- power-amp :
low power, so that the amplifier isn't big and heavy.
someone mention me about using class D amplifiers. Would this be a good choise? I read a bit about it, but it seems to be more difficult to build (you have to deal with high frequencies, for example), but on the other hand, it'll require a smaller heatsink/transformer..
Would it be a good idea to use ICs for the power-amp, or build it with discrete transistors gives better results?
- power supply :
depends on what I choose above
