    That's what was meant when I mentioned alphanumeric etching on the chip itself. Me too... I'm using watercolors now... Goodbye crayons.

    Hello, I want to reduce 12 volts to 7 volts, how many ohms do I need using a resistor?

    Using only one resistor in series with your load, that is your load must be used as the other resistance in order to divide the voltage by the ratio of the ohmic value of the now two resistors. You wish to make a voltage divider, that takes two resistors. Your load must be purely resistive &...

    are any alpha numeric characters etched upon the IC .That would be the only way. I have come across plenty of datasheets for designer IC Gesundheit ! ! ! I was trying to be helpful by requesting additional information about his query. You see English is my third language so something must have...

    Need simple overvoltage protection - can I use a 7805?

    It's good for 1.5 amps with appropriate heat sink.

    Behringer Ultrabass input section issue

    Quick check of VR3a to VR7a, contact cleaner for the 100k Ohm potentiometers & VR10, 10k Ohm potentiometer. It couldn't hurt it & won't make things worse.

    Rewindind motor stators ?

    A variant AC universal motor has brushes, they are popular in vacuum cleaners because they can run on AC or DC. It'd be nice to know what type of motor you have what manufacturer. As you can see winding complexity can be an issue...

    Blown amplifier part.

    Your safety, 0.1 microfarad, x3 capacitor is there to filter, suppress or attenuate a voltage spike, anomaly, transient, the source of which is your local utility grid that you plugged into. The capacitor let out its magic smoke.

    Blown amplifier part.

    Subclass is X2 used for home appliances and X1 used for industrial applications although both exceed X3 safety classification sacrifice is in size and price point it is why I keep asking for dimensions. This is the third time already jeez

    Issue With My Tektronix 2430A

    all it needs is a new NV ram battery. (just did this hours ago for same reason,) the book is clear, it says and I simplify, if CKsum fails, ignore all other errors !!! (that is because all amp offsets are lost and all self tests will fail) all 2430s do this and is a simple fix, replace the...
