For this piece to be trully impressive you would have to replace the tubes for so.ething more expensive but for the money I think it is a really nice piece , i recommend replacing blue diodes with light orange or none at all :)

Alienmoon The blue lights are only an effect of an LED, the Tubes should glow up Orange anyway if they're giving enough power.

R2VMinvic OrangeLED has lower voltage drop than blue, so increase value of limiting resistor if you change it.
