Basic Electronic Amplifier 9v to 12v Cigar Box Closed Guitar Amp

I'm using a vintage Stand-up Display Cigar Box. I bought this years ago, but I'm also using another box inside this one to seal it up. The box I'm using inside - I bought at a local cigar shop for $1. I'm also using an air filter from my work - when the ambulance is serviced I ask for the air filter to recycle the metal part on top.

It is hard to find parts at local stores, because Radio Shack has gone bankrupt. I use Epo - Electronic Parts Outlet & Frys Electronics, both are local stores, but they don't carry all the parts I need, so I'm forced to buy from online stores too. I couldn't find a 3-watt Rheostat locally, so I bought a volume slide switch instead.

Solder all parts to breadboard & add switches - power supply (I'm putting power supply on outside of cigar box, so I can use multiple power options). All switches and guitar input will be mounted to front of box.

Cut & Drill out your cigar box to hide all amp parts. Mount speaker - I'm using a large 10oHm speaker. I can't mount it into box, so I am going to glue it with PC11 to hold it to back of box. I'm using another cigar box to hide the speaker & seal up the box. Then I'm using the front cover of cigar box to hide all backs of controls. Then using a wire from an old car filter to cover front of box. Cut to fit.

Place everything in Cigar Box & wire it for 9volt or 12volt - Or both. Test amp. Everything sounds good. Makes a nice practice amp. Can be used with battery, Usb into wall outlet, Usb in car, or Usb on laptop...
