Op Amp Stereo Amplifier Sounds

I tested the amplifier using one of my vintage Walkmans and my vintage Sony headphone and it sounded great! It was very loud and that optional 10-µF capacitor really kicks butt. I have written down the mathematics involved and must remember to apply for a PhD one day at one of our fine English institutions. However, it would be worthless due to the corruption and political meddling in the education system.

Unfortunately obtaining an affordable plastic case is still a problem today as it was 20 years ago! However, these days we have pound stores and you can buy a metal compass box, which would work well.

Simulated Sound

If your computer has sound facility, you can hear what it sounds like. Just make sure the sound volume is 3/4 full. This is a YouTube clip from the Star Trek film, with the beastie boys Sabotage song.

This ends my light-hearted article on building an operational amplifier on a student budget. I hope you liked it and learned something.
