Please help with my Coliseum Bass head!!
« on: June 04, 2004, 05:40:26 pm »
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:

Any info anyone may have will be helpful.  There's a guy selling a service manual on ebay and I was going to pick one up, but I don't know if is is for the amp I have.

Thanks

Samie,

Look on http://www.richbriere.com/The_Sunn_Shack.htm. There is a complete schematic there for a Coliseum Bass amp. The one you have is a year or two later but should be pretty close.  The earlier ones are 300 watts @ 2 ohms. Look at the 1979 catalog at http://www.dangpow.com/~sunn/catalogs/ .On page 8 there is one that looks like yours and it says 320 watts @ 2 ohms. Could just be a specification change. Most of the changes I've seen in the Coleseum series were just cosmetic.
