***UPDATE***
Three great articles on discrete JFET preamp design:
- J201 preamp by Don Tillman
- MPF102 preamp by James Hawes (adaption of Tillman preamp)
- MPF102 preamp by Mike Martell
Hey, I am getting back into guitar and have wanted to put some of my EE design juices together and would like to build a guitar amp out of a couple 2n3904s.
I was thinking maybe two gain stages and then a buffer to match the speaker impedance.
The datasheet claims that they can source a max collector current of 200mA which I think would be well beyond what I need to power a small 4ohm 1 W speaker.
I'll just have to play around with filters to get rid of nasty harmonics and what-not.
I'm not expecting Marshall-worthy sounds, but just a decent project to work on. Sound realistic?
