Product code: Lot 36x Engineered Electronics Vintage top Solid State Tube-like integrated circuit
These are incredible 1960s grey military and industrial cylinders that each held a self-contained circuit. These have been in a damp location and are hard to open because the aluminum has cold-welded. The one I opened looked fine inside. I am not interested in selling them top individually. Usually these are listed for much more money. They're really cool tech for the early 1960s cold war period one has bent pins as shown. All of them will need their pins cleaned. Flip-flop, gated flip-flop, emitter follower, DC logic, inverter, relay driver, reset generator. These guys have fantastic pictures of these mini circuits: https://en.todocoleccion.net/old-radios-spare-parts/circuitos-encapsulados-vintage-engineered-electronics-circuits-vintage-nos-x16-unidades-unit~x236507490.
