[dragonz]

anyone explain what these are
thanks

I think you mean Tantalums, they are blue, brown or red blobs.

If you get yourself a maplins catalogue it has pictures of most components and a small description of it's uses, or you could try looking in the "FAQ" under electronic supplier links and search for a picture, or........
click here, the tantulum is the bright red / orange blob just behind the volume control

 

[dragonz]

is this an led?

 

[penance]

nope

 

[dragonz]

thanks you two back to the drawing board
i am trying to find out why there is a red glow from 2 led's
on a board on my cd player
see my other thread any help would stop me from a red scalp.

 

[Fatmarley]

If you turn the cd player off the red glow will miraculously disapear!

 

[dragonz]

yep thats right they are definatley leds and only come on when the equipment is powered up

 

[penance]

not tantalum caps then.........

 

[linedriver]

anyone explain what these are

Generally crap! Take them out and replace them with something that sounds good!

 

[dragonz]

so is there anyone with any idea why there should be red led's on a circuit board for my cd player. their has been someone suggesting led's are used to bias a current source,whatever that means

 

[linedriver]

Yes, Andy is absolutely right, they are probably either current sources or a diagnostic.

[dragonz]

being a bit thick could you tell me what it would mean if they were diagnostic.
thanks

diagnostic - i.e. to check all is well. Perhaps if they don't light up, something's broken, or a power supply feed's been interrrupted, etc.

 

[dragonz]

thanx for that
