    An Ampeg SB-12 came my way with no cabinet, so I got one from the folks at flip tops. Turns out the amp is modified and I think it's overpowering the standard speaker. from the photos here, can anyone hazard a guess about the modifications? Two extra caps and a very large transformer on top - so tall the cage needs risers to fit over it. I'm hoping maybe this is/was a common mod you might know about. Would like to know how much power it's putting out so I can put in a more capable speaker. Thanks! IMG_6879.JPG IMG_8510.JPG
