Trying to learn?

[perrytelephone]

I've recently decided at the age of 15 to start getting involved with advanced electric stuff at school so i could get a job repairing amps and guitars. But right now im still a beginner to this all so I ask for your help.

One of these days im planning on using those schematics to practice making a cheap and simple bass amp.

I figured that the Squiggle lines represent the resistors and that the Double I's represent the capacitators.

1. but does the plus and minus sign represent a transformer (or a power source)?

2. and do the 3 horizontal lines stacked on each other represent breakers?

3. And do the numbers above the ?resistors? represent kilo-ohms?

Any answers to any of my questions would be greatly appreciated.

Great idea...if you want to do this for a living one day, now is the time to learn and get a head start before college

1. but does the plus and minus sign represent a transformer (or a power source)?

No. That's an operational amplifier, or "op amp."

2. and do the 3 horizontal lines stacked on each other represent breakers?

No. That symbolizes ground.

3. And do the numbers above the ?resistors? represent kilo-ohms?

Yes...10k means 10 kilo-ohms

Thank you very much.

Do you know where i could purchase an op-amp.

...Or your local Radio Shack if they still carry electronic components...

I would recommend that you buy a soldering iron and try to build a kit first. There are lots of audio kits available...

Thanks for all the help man.

That isn't the best circuit to learn from. It is missing some things, such as the power supply. You will need a +/- power supply for the opamp to work properly.

I would recommend trying this project first:

It builds a very cool one transistor booster pedal. With probably close to the gain of that bass amp. Plus this project shows all the tools and parts needed to build the booster.
