My KDA50 was always last on the bus - in fact it was always
in the very left hand slots in a BA21x cabinet ... saved
having to scrounge load boards from somewhere!

It was usually a DHV11 or similar that I had to worry about.

Thinking about it, I did have a KDA50 in a BA23 - there
obviously the straps had to be in - although my main concerns
were not setting the PSU on fire and having enough space 
internally to house the SDI leads out to the cab kit!!
