This is a fully assembled carrier board for the Korg Nutube 6P1.  This is the same as the one that is supplied with the evaluation board.  It can also be used to interface to a standard perfboard for prototyping. These normally are built with SIP pin headers that mate with IC sockets.  They can also be provided with 0.025" square headers, or with no pins or headers installed.  If you would like one of these options, please note it in the order notes. For more information, please visit the Nutube US website (in their infinite wisdom, eBay no longer permits me to post the link here, so you will need to do a web search). Flat rate shipping via FedEx to US destinations is shown.
