Hi guys.. I was doing my Friday quarterback with a broken classic phone.. And saw this component: (circled in red)

https://www.electro-tech-online.com/attachments/image0269-jpg.33743/


That's the best picture I could get. It's a glass tube just a bit bigger than the standard carbon film resistors, and inside the glass vial there is a thing which looked like a carbon resistor stripped from its film. Is it just a regular resistor?
Would be nice if it's a sensor or something. ;)

It looks like it might be a diode, especially since you mentioned the "glass tube". Does it have a band on one side? This is just either just a white or black line that goes all around the circumference of the component. That will tell you which ternimal is the cathode. It could be a zener or gernamium diode. If you have a diode tester on a multimeter, check and see if it is a diode. If you don't, diodes should have a certain amount of resistance one way, but not the other. This will also confirm whether or not it's a diode.

Well I've tested it with a 9V battery and a motor, it did act like a diode except the output current is incredibly low. The motor turned like a pussy. I mean, IN4148s are one of the lowest current ratings for standard hobbyist application but a regular motor turns quite well for it, but this is just too low.
