I bought a used coliseum bass head and I don't have a clue about it! I noticed that there seems to be several "coliseum bass" models but I have no clue which one I have. I don't even know how many watts it is, only that it is LOUD!! I am thinking it is a mid-1970's head, but I am not sure. There is a pic of one here:

Thanks
