Box may have suffered shelf wear, tabs may be torn, may have price stickers or other writing. Unless otherwise mentioned, I have not tested the NOS tube but will refund or replace tubes that do not meet original specifications. While stock is available, I will attempt to meet brand or sub-type requests that do not require detailed inspection. Some types have additional stock or brands available. Mixed type quantity discounts available for most vacuum tubes, add all items to cart and pay together. International buyer is responsible for any import fees or taxes.
