looks clean....decent deal, although that is the lower end bass cab with the SUNN 15 and not the JBL d140.
That head is pretty much the same as a 200S head. The cab is only like 11.5 inches deep, whereas the VERY desire able I-40 single 15 that is JBL loaded is like 14 inches deep and ported differently.
The head alone, if it doesn't need any work, is worth the asking price alone.
I've got a couple of them. Love old SUNN stuff, especially the 200S and 2000S.
