"That's brilliant Scott, thank you! I'll have to order up some components and give it a try. I'll crack this thing yet!"

"The power supply of 9 volts is adequate. Unless the IC is the LM386N-3 or -4, which are rated at higher power supply and output. Likely, the one on yours is the more common LM386-N1. The circuit you showed related to the kit has a few components…"

"Thanks for the great advice, Scott. My kits arrived in the week so I've been having a bit of a play with them. I've made one up as per their instructions, without volume or gain controls just to test it and I've mocked the circuit up…"

"Yeah, crazy to think I started with a stick in a box, and wound up making these. Thanks Ted."

"Thanks Wayfinder. Lots of info on the Internet about the little LM386 amps. Amazing sounds from such a simple circuit. I've built and sold many of them, including two I sent off this morning. Decided to step things up a bit, and am currently…"

"Hi Mark, the kit you mentioned looks like it's designed for an MP3 player. Which is why the 1 & 8 pins are not shown on the diagram/schematic. The kit amp is meant to sound as clean as possible without distortion or gain. No worries. You…"

My first Build

So this is my first CBG, very much a prototype and a great experience to iron out wrinkles in future builds. Made a few rookie mistakes which meant that the fretboard is a bit short! Got a few issues to iron out, buzzing frets etc., but I've learnt…

"Thanks for the advice guys, much appreciated. The company I'm getting these from sell mainly to schools for electronics courses on the national curriculum. As such their website has lots of resources like circuit diagrams and troubleshooting…"

"You can wire in volume for sure, and if you have specs you can surely wire in a gain pot, at the least just a tone pot.  For that rig, you cut the wires between the board and speaker, and wire volume and tone in between.   Cool circuit you…"

Mini Amp help

I'm planning to make some mini amps out of old tins and I've been looking at kits based around the LM386 chip. I don't want to buy them from the US or China (I'm in the UK) as I'll have to wait a while and pay import duty. I've come across a UK company which do them very cheaply, £2.60 including a speaker and battery connector.https://www.kitronik.co.uk/2154-mp3-mono-amplifier-v20.htmlThe problem is they don't have volume…See More
