    Can anyone help identify this MOSFET?

    Welcome to the forum. The generic part number is 16N04. I haven't been able to find it in the package yours are in, only in a 6 pin + tab package. You're probably going to have to find another part with similar spec's.

    2N2222 questions

    The way I see it assuming the LED is a 2V with a series 180 ohm resistor, current consumption will be about 22mA. Multiply by 7 LED's which brings it up to a little over 150mA. I think a 2222 can safely do this.

    Roberts Radio RD60 Power problem

    Welcome to the forum. Whether it is an AC line cord or a transformer with a barrel plug, inside the recepticle on the radio there is a switch which, if bad, can prevent the battery OR the transformer (or AC line) from powering the unit depending on which side of the switch is not making contact...

    555 Trigger

    I checked the circuit. The schematic and parts values above are accurate. As I mentioned, this is not a preamp per se, it is only sending a spike to an ADC. This circuit has been in use for 10 years and we never had a problem with it. You can breadboard it and try it in "real life" with a scope...

    How Often to change Air Filter in Purifiers

    It is usually in the owner's manual. We have 2 different ones and both recommend replacing in 1 year. One of them recommends using a vacuum to clear the incoming side once a month or more if you have pets that shed.
