The Melz LP-4 is a bizarre Soviet-produced linear trochotron in a large acorn-style envelope. Although the LP-4 is electrically similar to one of the linear designs described in the Alfven-Romanus patent, the LP4 is pseudo-circular, with its linear electrode array curved into an incomplete ring to facilitate installation within a compact cylindrical envelope.

Unlike most beam switching tubes, the LP-4 is not shipped with its magnet pre-attached. The external magnet is attached and aligned at the time of tube installation.

The LP-4 is packaged in an extremely unusual 26-pin oversize acorn envelope.

Unlike many Soviet tubes which are bulk-packed, the LP-4 is individually boxed and includes a datasheet.
