    Hello,

    I need help identifying a few unknown components:

    First one:

    Back side: [​IMG]

    NEC AC2501F 09 L:

    GENTECH SCOTLAND G43E X586 50 85:

    Thank you in advance!

    My guesses are: trimmer capacitors, a germanium power transistor, and I'll pass on the third one.

    My guesses:
    1: Variable/trimmer air capacitors (no guess)
    2: A triac (since the terminals are labelled T1 & G)
    3: A mercury wetted reed relay (since it has right way up)

    This sounds reasonable. Thank you!

    I have a new challenge though. Does anyone have an idea what kind of components are these?

    Number 4 (it has 7 pins; 4 on one side and 3 on the other):
    [​IMG]

    Number 5 (feels quite lightweight, its mass is just ~7.75 grams):

    Thanks in advance again!

    4: A signal transformer.
    5: A dual PTC resistor element, used for automatic demagnetizing of CRT's.

    These are somewhat exclusive, particular, and old parts. Why do you ask; are you intending to fence them on the Bay? ;)

    Thank you a huge lot for the answers! Well, I just happen to have these parts around. And I'm a very curious person. It's of a great interest to me to discover some kind of odd electronic parts I've never used before. Selling them isn't in my plans so far. However, if I don't find any use for them and someone would like to acquire these, I am willing to even give them away. Or, well, put them for sale on eBay... ;-) Thanks again for sharing your knowledge!

    You're welcome.
    You sound just like me.. ;)

    The part number on the triac btw. is AC25DIF.
    V(DRM) Max. Repetitive Peak Off Voltage = 400V
    I(T(RMS)) Max. On-State Current = 25A
