Converting a cassette player/radio--where do I start?

Hi! I bought an old cassette player/radio at an estate sale (really cheap!) and I'm wondering where/how I start in converting it into a guit amp. I've seen a few vids of some Australian (?) cat doing…Continue

Nice looking little amp you got there Jeff.

Looks like I’ve got me a little traveler amp ....

When I made my dual chip amp, the 220uf caps on the output line was too bright. I ended up using 10uf caps to tame down the brightness. So try the 10uf cap.

Comment by Scavanged Sound (Pete) on February 24, 2017 at 7:31pm
So the standard 220uf electrolytic cap I'm using is the culprit? I have some 100uf and 10uf..time to experiment. I'm thinking with the amount of high end I have the 10uf will be better. The highs are so sensitive you can hear knuckle hair rub on the strings
Comment by Paul Craig on February 24, 2017 at 6:04pm

Capacitor on the output line. low value to cut highs - high value to cut bass.

Sorry everybody....just realized I messaged the whole group rather than post my question here

Right after I posted my request I saw a post by Paul Craig. It's exactly what I've been searching for. It's over there on the right side if anyone else is looking. Thanks Paul for doing that drawing and sharing.

Pete, look up on this page, see Paul Craig's discussion "Dual LM386 Chip Amp". Lots of info and schematic there. I've built dozens of LM386 amps (single chip). I find that the speaker and enclosure/box have a huge affect on volume projection and tone. For example, I add a line-out switch and jack to my LM386 amps. This allows the user to play through the speaker in the amp box, or flip the switch, connect the "line-out" jack to a bigger external speaker cabinet with an 8 ohm load for big sound.

Hey there fellow amp builders. Does any one have a decent schematic of a bridged LM386 amp. I'm currently building single LM386 circuits for my cigar box amps but I want something with a little more kick for a couple suitcase builds I want to do. There are lots of schematics on the web but a lot of them don't list values for components or include hooking up volume, gain, ect. Thanks in advance

Hello, just joining the group. I ordered a 3 watt Tone Monster kit and a couple cases to make #1. Looking for some fun. .. Dave
