Some of these type sell for hundreds new or rebuilt, so there may be value in parts or rebuilding these. Here is the deal, we picked up a box of surplus used boards at a sale of tools and misc industrial stuff. We know nothing about them so if any are untagged please assume they need parts or rebuilding so that you will not be disappointment. Due to the age, we would recommend replacing electrolytic capacitors as a start. Some may have bent pins bent over component leads, etc, Please look at pictures. Most need some level of cleaning. If you cannot tell from the pictures that you are sure you want it, please move along. These are only for sale to those who can tell by the picture that this item is something they can use. We are not taking returns. Some boards have multiple part numbers so we try to get the numbers in the title and/or pictures. Search our store as there are similar ones that came in this lot that vary in part #s. There will be no refunds, no partial refunds, no returns (unless you get something other than pictured) Notes : SEE PICTS apprx inches 14 X 7 X 2.75 INC HEATSINK 3.8lb unpkd wt
