Cathode-ray tubes for television, including video monitor cathode-ray tubes, monochrome, used in black-and-white sets and monitors.

CRTs are heavy and can implode, so pack with thick foam, state size and phosphor, and note lead glass disposal rules. Electron tubes and semiconductors are static, moisture and shock sensitive: ship in anti-static packaging, trays or reels with desiccant, state part number, rating, package and lot code, provide RoHS declarations, and check export controls on high performance microwave tubes and advanced devices.
