Are you thinking about making a stereo amplifier? If you are,then it's the right place! Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. It is originally designed for portable cassette players and radios, but it can be used to make a pretty decent stereo audio amplifier for an iPod or mp3 player. It requires very few external components and can run on as low as 3 V power supply.

Unless you diagnose the issue properly, you're just as likely to kill replacement parts as well. Devices like this?
Unfortunately most of the time you're better off just replacing them. Stygian Shane , Apr 30, Plug it all back in and measure between pins 9 and 16 for a steady DC voltage.
I can see bottom right corner appears to be a power input from whatever power source it has.. Joined: Oct 20, Messages: 2, Location: Perth. Dr Evil , May 1, Joined: Jan 21, Messages: 3, Location: Saigon.

It sounds like you were measuring the transformer output. Jaycar has some great kits that do not involve mains power too. Mickatroid , May 12, Was not trying to be condescending, just safety first is all. Some stuff can kill you long after it is turned off TVs and Microwaves are examples. On the topic of too good to throw away I wrecked a cassette deck for parts a while ago. Heaps of fun. Mickatroid , May 13, You must log in or sign up to reply here.
