PL meters - amber LEDs

[fitz43]

Are there different colors of amber LEDS?

Not sure you meant to leave the amber in there but if they are behind a dial or meter etc a filter can be used to create colors, just like the multicolored displays you see on receivers, tape decks and others.

Yes

 

[fitz43]

Yes

Darn, it's not like they have a part number stamped on them that I can look at to see what was used.

Do you still have contact with who installed them??

 

[Gepetto]

If you install the White Oak light board, you can use any color LED that you like.

 

[laatsch55]

Yep, that's what we have planned Joe, just trying to get the color code?? Or number?? How do they code those things??

wavelength (nM) and intensity (mcd)

Why amber? Is that the desired color?

 

[laatsch55]

Yers to match the 400 in the first post. It has amber.

You could use a bi-color red and green LED to create your own blend.

Are they in fact amber LED's? Or is it possible that either they are old lamps or like happens with Marantz that there is an aged diffuser that is creating the amber appearance?

They are actual amber colored Jim.

Ok, it was just a thought.

I have seen a few green Marantz's. lol

To me it just looks like a poorly lit image under tungsten light, but as was stated you can create quite a few meter colors with LED's.

My old Sons of Ampzilla have that look, but it is age that is causing the yellowed color.

That too. I have owned a few cassette decks where the meters background and or bulbs have yellowed with age.
