Thank you for viewing. Toshiba 12AX7 vacuum tube set of 2 Comes with the original box. I do not have measuring instruments or a suitable operating environment, so the operation of both items has not been confirmed. These items have been stored in a cool, dark place for a long time. Therefore, they are sold as-is, for those who understand and accept their current condition. Please check the condition in the photos. Everything shown in the photos is included. Thank you.
