It’s official: I’m an EE
10 02 2007A month ago, I inherited a stereo receiver/amplifier from Karyna. She got it from Craigslist, and it was starting to ‘go bad’—some crackling, and other non-niceties in the sound. She got a new amplifier from her parents, and decided to give me this one. As for what I’d do with it, I’m not too sure.
So I ordered a service manual from stereomanuals.com. Despite their horrendous website and slightly cryptic e-mails, I managed to get the right service manual. And it is beautiful. They do a bang-up job on reproducing the manual, and they are rather prompt in shipping. So, I highly recommend them—in spite of their horrible website.
Now, I’m looking at the circuit layout, the block diagram, and everything; thinking to myself: damn, that’s complicated, but I could make that! It’s obvious now that I’m ‘in love’ with circuits. I have a specific task that’s interesting to me, and I am thinking about how to build it.
Anyways, I need to spend some time with my receiver/amplifier and figure out what’s wrong. By looking at the block diagram, I’ve realized that I can cut out 90% of the circuit, as it is obvious it has nothing to do with what’s wrong.
Ahh, so it begins. I’ve seen this before. I had a friend who got a master’s in EE, who was also a DJ. He realized it was cheaper to make his own speakers, and was soon building speakers in a range of different sizes for all of his friends and family. So, when are you starting up your own speaker business?
Hmm… speaker business? Maybe. I’d have to look into it. But perhaps I’ll start as an Amplifier/Receiver business and move from there.
