I draw a blank at that one! I vaguely remember Mike Sells and/or Mike Law working on something called a COOBE (the ‘COOBE’ stands for ‘COmmentator’s Outside Broadcast Equipment) but I have no records of that at all. It would have been a couple of very high quality mic amps and probably a ‘flat’ effects return mixing into the output, and most likely a headphone amplifier facility with talkback input. The date would have been 1976 or thereabouts.
