Lot of 4 pcs GU-50 (??-50) Russian high power pentode tubes, NOS. The GU-50 is a power pentode vacuum tube intended for 50 Watt operation as a linear RF amplifier on frequencies up to 120 MHz. It is one of the more unusual types of tube because of its non-standard 8-pin base and a metal "cap" (not connected to any of the tube internal elements) with a plastic "handle" on top of the envelope - which is meant to ease extracting the tube from its socket (especially when the tube is hot). Eqivalents LS-50, P50, FU-50. Produced 1960s-70s by Ulyanov Tube Factory, Ulyanovsk, Russia. Military equipped, high stability and durability. All tubes are fully tested and approved.
Condition:
New: A brand-new, unused, unopened, undamaged item in its original packaging (where packaging is applicable). Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.
