    Removing Components for Testing versus On Board Testing

    It doesn't work that way, otherwise everyone would be a brain surgeon Are you suggesting that being an electronics technician is equivalent to being a brain surgeon?

    But you need to know or at the very least be able to trace the signal up stream or down stream I know you have to have a schematic to show parameters at various points which if not met, indicate a malfunction and a possible general location to zero in on. You don't have to be an electronic...

    Thanks. Now I know what to look for in service manuals even without experience.

    I meant based on the specifications as listed on Amazon. Is this small cheap scope better than the DSO150 if you look at the specs and based on thos specs, what could you do that you could not do with the DSO150? I'm talking about specs like "sample rate", bandwidth, etc. that are listed...

    Speakers and Bass Frequencies

    Yes, can use multiple small speakers to get the combined needed low frequency air movement. That is the answer to my original question, I suppose. So the answer (according to you) is that multiple small speakers can do the same as one large speaker.

    Bluejets suggested I get the small cheap DSO150 oscilloscope to add to a basic tool kit to get started. That doesn't mean I would immediately use it as soon as it is delivered within the hour. I seen the other small scope for about the same price, around 40 to 50 dollars, and was asking him...

    Removing Components for Testing versus On Board Testing

    "You should be able to determine - to some extent - what area of a circuit is at fault" So how do you determine that?

    Speakers and Bass Frequencies

    The Bose is one I was thinking of in that very small cabinet. However there are multiple 5" speaker arrangements (and cabinets) that go down to 30 Hz.

    Removing Components for Testing versus On Board Testing

    I looked at some basic youtubes about testing components to see if they are bad. The idea was to unsolder one end of the compnent to take it out of the circuit to test it. That seems like a very cumbersome way to test if there are hundreds of components. Would'nt it be better to test the...

    Bluejets I don't know much about oscilloscopes but seen this one on Amazon along with that DSO150 you recommend. It's around the same price. It has larger numbered specs if that makes any difference. What could you do with this one that you cannot do with the DSO150...

    Speakers and Bass Frequencies

    Researching about bass reproduction in stereo or music speakers, it used to be that 15 inch diameter speakers or even 18 inch in big enclosures with tuned ports were required to get the best bass response. Now modern small combinations of speakers even down to 4 or 5 inches are used to get...

    So is a multimeter enough to do some attempt at repairs or do I need some other gear? I already know a soldering iron is needed.

    OK youtube. I'll look there for something relevant. . How about oscilloscope? Do you need one of those? What's the use of one? Seems like anyone doing any kind of repair has one.

    Learning Electronics for Everyday Practical Reasons Non-Professional

    How much electronics theory for a DIY fixer upper? Would an oscilloscope be a tool you have to have? How about other electronics measuring gear? (I already have a couple multimeters) Keep in mind I don't want to be a technician or engineer and not even a hobbyist who loves electronics kits and...

    Learning Electronics for Everyday Practical Reasons Non-Professional

    I suspect that DIY electronics repair is more involved than DIY replacing spark plugs or changing brake pads. The principle is the same I think, but the skill and knowledge level is different. That's the puzzle piece I'm trying to find. Tell me that unscrewing a spark plug and replacing it or...

    Learning Electronics for Everyday Practical Reasons Non-Professional

    I just used the auto repair example to have something to compare to regarding DIY, around the house repair. There are people who can do quite a lot of DIY auto repair without much knowledge and little experience. I suspect that electronics DIY is a lot different and requires more knowledge and...

    "The actual skill is learning HOW MUCH KNOWLEDGE you need to make you competent" But how much do you need to fix typical home electronics like TV,s radios, computers, stereos etc. (smartphones-forget it) Great post and pretty much what I'm getting at, although I don't think I would want to do...

    "In terms of knowledge, electronics can be far more complicated than motor mechanics BUT...... how far you're prepared to go" Yes that's the crux of what I'm asking. But more complicated how? In what way? When do you say, "Forget it. I'm taking it to a shop" or just buy a new stereo (or...

    Learning Electronics for Everyday Practical Reasons Non-Professional

    Well yeah I know its about more than replacing parts. I know that you have to have at least a basic understanding of theory and yes I can use a multimeter. As far as years of experience, I don't have that. What I'm asking is, would it be practical to learn enough to repair some electronics gear...
