Tested this unit and it worked well with no crackle on the faders. I did have a bit of a connection issue on the back so the inputs could be cleaned, which is to be expected with equipment this old. The power cord has been replaced. There are a few marks on the case and in the back some damage as shown in pictures but overall it is in good shape. It is very slight but it does appear some of the fader knobs might have a slight bend but it is hard to tell and works as it should. This is being sold as is due to the age of the machine but it did work well on the bench test.
