eBay B&K CR-64 CRT Adapter Still in the original box. It looks like new to me, though it has been out of the box before. I'm sure these were used with B&K 465 and 466, but I think they might work with the earlier 400-series testers as well. It looks like the same socket to me. Shipping: Domestic: Free! International: I have had no complaints and no lost packages. However, not all shipping options allow tracking or insurance. It seems to depend on the destination country. I will use the method of your choice on inexpensive items, but will assume no responsibility for services not available by your chosen method. I often do not list 1st Class International shipping as an option, but will use it by special request. I expect my buyers to understand the services available in their country better than I do. Communication: I'll answer questions quickly in most cases. You will receive a shipping notification with tracking info and a short message from me. I will not otherwise communicate with you unless you have a request. I will give feedback on all transactions. I have 100% positive feedback and will do my part to maintain it. Thanks for looking!
