re: 620

I am new here and this is not a new post but i still have a question. I have found 9 bgw 620b amps, 8 work, 1 for parts. I have used 5 of them for subs at an outdoor show with superior results. Fine amps as you know. My question is these are mono amps and all i've seen are two channel. These have no knobs one the face, only breaker, power and clip. Screwdriver attn. on rear, one amp mod. with 12 power transistors. Is this something made for a special purpose and they had "620b" cases overrunning the inventory? They were removed from a major amphitheater. Any info is greatly appreciated. I'd like to know what i've got, these things seem to put out a ton of juice. thanks.
