I bought an old Fischer tape deck from Goodwill for $8 and I'm desoldering components from the circuit board for use in projects so I don't have to go out and buy components at high prices in comparison to $8 for an all you can eat buffet of capacitors, transistors, resistors, etc.
I'm able to identify the resistors and capacitors, they are clearly marked, and I have a resistor color code cheat sheet printed out. I've also identified some ICs as audio amplifiers. I have found that I can identify the transistors as well.
What about diodes? The only markings I can see are D, 8J, and 135. I typed these into Google as D8J135, 8J135D, and 135D8J with no results. It is black with a grey stripe and lettering.
Another pink glass diode I was able to identify as a Zener diode.
I also found these blue cylinders, plastic outer casing, with a schematic symbol on the circuit board that looks like a symbol for a lamp, but it is not enclosed in a circle. It just looks like a curled loop symbol. I looked up inductors, but it is not an inductor. I also found this green box with a screw top. The top can be unscrewed all the way, revealing a center post thing. I have no clue what this is. A variable capacitor, maybe?
Here is a pic of all components, the symbol of the blue cylinder, and three views of the green box thing:
Anybody know what the blue and green things are or what kind of diode that is?

It is indeed an inductor, why do you think it's not?

Looks to be a transformer to me
Diode looks just like a standard 1 amp rectifer diode to me, but looking ain't specific specifications.
Wow, thanks! I have no idea what I will do with these parts, but at least I now know what they are.
I swear this tape player was a gold mine of capacitors and transistors! I probably scored $50 in parts if they were new in packages!
PS: I didn't think it was an inductor because the symbol didn't exactly match what Google image search brought up (I typed in this: inductor schematic symbol). So I wasn't sure what it was.
I wouldn't rely on the electrolitic capacitors you harvested. Those, being so old, are very probable dried out by now (could be one of the reason they threw the device away).
The Blue can is indeed an inductor.
the Green can is a tunable inductor for RCL circuits
the diodes may be 1N135 diodes. 1 amp rating
If I were to pose a guess on the Blue one, it's most likely a 7900 uH inductor
