Tested, fully working Conrad-Johnson MC step-up transformer, produced in the early 1980s. Given its age, the item is in very good condition, although as with most used items, there are minor scratches and blemishes here and there.Sound quality is Conrad-Johnson at its best – huge sound stage, super quiet, superb detail. These almost never come up for sale, so don’t miss this chance to own a piece of very early Conrad Johnson history.Questions welcome, and happy to provide... more photos.
