Is that the same as the EL that was used in the 1980's on lots of old
stereo gear ? Ie.. you'd hit rewind and some little backlit
glass-and-silkscreen template would say "Rewind" in blue or green or etc..
I LOVE the way that looks. That's one of the reasons why I love the Amiga
CD32 (not that I own one.... yet). It looks like a hifi stereo component
from the 1980s. I have a Kenwood electronic EQ and spectrum analyzer that
has all kinds of EL elements on the front of it. I still use it daily.
