12C5 / 12CU5 Westinghouse VACUUM TUBE - GUARANTEED

Westinghouse 12C5 / 12CU5 Beam Pentode VACUUM TUBE, in box. Part of a large cache of tubes - this one comes from my personal collection of tubes, many dating back to the 1950's to 1970's. Tubes have not been recently tested, but are nevertheless GUARANTEED against DOA. Images do an adequate job of representing the item.
