for someone to make themselves look smart: What is the queer little
blue
thing labelled '100HX-6bB' [sic] with what looks to be a blue 'pull
out
bit' slap in the middle of this board from one of my mics:

???

(Doesn't say 'not a resistor' or 'not a capacitor' so I'm stuffed!!
:-)

I'm assuming that is a switch - doesn't it poke through the case?


Nope.


And
no doubt -6bB is a typo for -6dB.


I would have thought so!


Could it be a low-cut filter?


At 100 Hz?


Try
pulling the blue bit out and see what happens.


Bugger that...


Or does it move
sideways?


Bugger that also...


Doesn't look like it will, but you never know.


Looks like it!

(If no-one here knows, I'll have to file it under 'Gubbins' and let it
pass! :-)
