Korg Wt-10a precision tuner

Although most of this team is in great shape the battery compartment can sure use some TLC. There is no corrosion but it has a strange connection that goes from 9 V connector 4 AA batteries. The 4AA battery holder is very beat up and may bot function but the 9v battery connector is fine and has no corrosion. This unit works fine off power supply although I do not have one for at the moment.This is a very accurate tuner. It has a built-in stand and a case. The case is a little beat up and has a small tear near the zipper but it still functions well as a case. These old tuners are getting hard to fine and would be great on the workbench. I have great feedback because I try to describe things as best I can and I try not to gouge. I ship fast and pack well. Thanks for looking.
