Diode Switch

My doorbell has chimes rather than just one ring or buzz and now I am told I have a bad diode. What's a diode?
Where can I get one? Where does it go exactly....in the doorbell switch at the door?
A diode is a one way switch that allows different switch patterns to be used in expensive systems. You can get what you need from the electronics repair stores where the TV guys go for their parts.
It goes into the door bell assembly, and pay attention to the direction as it only works correctly one way. You can't do much harm hooking it up wrong, but it won't work right if you do.
You may find a printed circuit board with it attached, or it could be independent. It will have a band around the plus end. rating will be in amps, possibly as much as 10 to 20. Match the size of the unit for best results, and it may be silicone, careful. they get hot. Sorry I can't be of more help, but we're likely to be thousands of miles away.

RCL Diode Snubbers with Rudy Severns
How do I make a simple electrical circuit that oscillates as a sine wave?
The only electronic supplies I have are: Capacitors, resistors, diodes, switches, light bulbs, wire, and a bar of ferrite to make an inductor.
can't with those components. You need something that can provide gain, like a transistor or an op-amp or a vacuum tube. Plus DC power to power them.
