    Thyristor and switch controlled power on.

    In a deep well......... Apart from the point which you already missed, apparently, the off current has to be handled by the commutating switch. In your case the main power or off switch depending on which circuit you use. Hense, the whole circuit is a waste of time.

    Thyristor and switch controlled power on.

    As I said, you are defeating the purpose of the entire circuit as the starter current can be anything for 600 to 800 Amps.

    Thyristor and switch controlled power on.

    The SCR will latch on by pressing the start push button and then remain on indefinitely until the main power switch is operated (Under high current condition I might add) which in effect, negates the use of the SCR in the first place. Instead of offering possible circuits to do what you may or...

    Like anything else, years of practical experience, years of study. Even then there are a lot of dead heads out there, that's just the way it is. Well known there are many good pilots out there for example and at the same time there are many who will kill you. Just accept it and move...

    Help identifying USB connector for Dell docking station

    You'll find the pcb is for either/or. There's only four pins to each socket afterall. The wrong colour....well I never. Still don't know how you know it is shorter if indeed it is.

    Help identifying USB connector for Dell docking station

    ....................question still remains, how do you now the ones I referenced are NOT the standard used. Anyhow, just nip the ends off a couple of usb extension leads and let them hang out the back.

    Help identifying USB connector for Dell docking station

    You didn't provide any usable dimensions so how would we know. They're for the most part, a standard size so I would be surprised if it did not fit. Don't know where you obtained dimensions off the quoted site anyhow. Good luck.

    Issues with amplifier

    With lack of any real usable data, I'd say it's broken.

    CD Player Won't read disc #2

    Time to dig deep and get a new one/two. Not a job for a newbie ....actually not a job for most qualified repairers these days. Simply not economical/possible to repair/replace laser read heads.

    Best driver choice for LED line lights?

    I'd be going back to where you bought the led strips as they would more than likely have the correct number and type of drivers required.

    Sony SLV-E780 Power Supply Issue – Clicking Sound, Need Help Identifying Faulty Component

    Remove or at least, lift one leg of the cap. With electros, make sure they are discharged first. A 10r 5 w resistor will suffice. For testing, buy a $30 component tester, best purchase you will ever make for the price. Use a series lap tester to avoid blowing fuses.

    7v seems an odd voltage to run dash lamps, however your 12v supply will pop them every time.

    Coffee grinder problems

    Motor is more likely a series AC motor. You reaĺly need to take a closer look at the motor first up. Look for signs of excessive sparking ie. damaged commutator, excess wear in brushes, burnt smell around the motor, does motor turn freely. It should be possible to run the motor indepently of the...
