Missing a knob and front plate screw. I've had this for almost 30 years. I got it at the Shure Brothers employee store in Evanston. It was one of three out of Sydney Shure's test bed, where you found the Neumann record cutting lathe on a floated floor inside the bank vault.I will double box it. It is an awesome piece of gear, and from the test bed of a serious audio contributor of the 20th century.All passive, and all good. I rarely used it. It was more of a conversational piece.Being sold as-is due to age and it is passive resistors. It still is all good.Please ask any questions prior to bidding.
