I purchased this amp from an elderly gentleman whose family purchase it in 1963 ..it was manufactured either in late 1962 or early 1963 im not expert on amps by any means ..but it sounds great and all original components with the exception of a relacement leather handle ..the original oxford speaker was professionally reconed by webber ..the amp was cleaned by amp tech prior to me purchasing it .the tremelo on this amp is amazing ...this amp is in great shape to be 55 plus years old ..
