This is a Great Sherwood Integrated Amplifier. It has been fully tested- serviced and all functions work great like they should. It is clean with very little marks if any. Please ask any questions you may have prior to purchase. Thank you and please check out my other Items in my Ebay Store. I usually ship within 5 business days of received payment not including weekends and holidays. I will be posting a video so you can see and hear how great it works and sounds.
