ok it is not a the rack it is the actual  module that  slides in the rack
but blue is one of the delta colors as I recall!

anyway  since I have some green, never been used components that I got as
spares for this  I think I need to find a green rack and a few other
components  to complete a second unit.....

heh heh went thru this with apx- 6's but this takes more room!
