    Power supply for AMP in CAR

    MP, Now that you found the Zapco circuit, this is only one of many in fact most of the circuits I have seen and repaired have no emitter resistors. Question is how do they get away with it? All this equipment is out there working day after day and they are all designed wrongly?? Ante ::)

    cable route detector

    thedreamer, It is possible to detect if it is power or a nail but the current cannot be measured this way. There are cheap detectors for this making a LED blink for power and lit constant for a nail or pipe. If you need to measure current there must be a known distance between the wire and your...

    Power supply for AMP in CAR

    MP, What is protecting the transistors in the Zapco circuit from destruction if the current starts to flow unequally through the emitters ? Ante ::)

    diode information reqest

    Steven, The d40d5 is as far as I can see a transistor NPN 1A 6,25W 200MHz and can be replaced with BD 419, BD 519 or BD 529. This is from an old semiconductor databook. Ante ::)

    HELP ? ATX PSU LEADS

    Hi, MARSMAN Mars is obviously connected to the World Wide Web these days. Welcome to this forum MARSMAN! Seriously; what you should watch out for is the voltage drop. A modern CPU consumes a lot of current and you will get serious voltage drop especially if you use standard wire. I think 5-6...
