(NEED HELP PLEASE!) 1w Amp build
« on: June 01, 2018, 07:12:36 AM »
Hey I'm wanting to try my hand at building a simple portable 1w Chime practice amp from ebay  parts (90% of the parts are from ebay) and I'm still very much a biginner at reading schismatics and even newer at working from them so can someone tell me if I'm going in the right direction please? I know I can just get the pcb for this but I want to learn how to go through the posses of bread boarding and so on. I'm nerviness about plunging it in because I don't want to break any of the parts...

Kind regards
Justin

This is the bread board


This is the schismatic

ok, here is a very very very crude drawing for ya....




dont worry about the diode, and the 4.7k and led...they are just for led indicator and

reverse polarity protection....this should get it up n running...

observe the fet orientation.  8) have fun. cheer rob . ;)

bt, hook up a much better /bigger speaker.... 8)

It sounds really good even through the tinny speaker. Do you know what info I would need to look up to find out more about making small amps and peddles or what basic info I need to know to make them?

i would say build a couple of stripboard/vero projects....just to get your feet wet..(google search vero projects)

then move onto breadboarding....plenty of vero projects out there, or even kits...

good luck dude. its addictive 8)

I've done a few projects like that. I'm wanting to understand how to make my own peddles and amps but I'll keep looking for things that could help. Thank you for your help though.

Hey I had posted on another forum and I was informed that the circuit wasn't going to last if I wanted to do more with it. I was told to look at the diagram that the data sheet offered but I'm even less sure how to put this together corectly

hi, that is the basic data sheet info.....it doesn't include the FET input section , which sees a guitar input. :)


'' I was informed that the circuit wasn't going to last''

really why?...it will be fine. (with the FET input section)
