Is this 5U or 3U format? I can't work it out.


Hi, what is pictured here is a 5U MOTM style module. See: http://www.modulargrid.net/m/other-unknown-cs80-com-gx1-bandpass-filter-module

But Old Crow may have, at least at one point, offered just the PCB for sale so maybe someone made a DIY version of it but they didn't have a proper picture to use here? ? It's a great sounding filter regardless! :-)
