I-valve isikhulumi noma i-tube amplifier iwuhlobo lwe-electronic amplifier esebenzisa amashubhu e-vacuum ukukhulisa i-amplitude noma amandla esignali.
Izikhulisa-msindo zamavalvu wamandla aphansi ukuya kwamaphakathi zamafrikhwensi angaphansi kwama-microwave athathelwe indawo kakhulu isimo esiqinile ama-amplifiers ngeminyaka yawo-1960 nawo-1970.
Ama-valve amplifier asetshenziselwa izinhlelo zokusebenza ezifana isiginci ama-amplifiers, ama-satellite transponder afana ne-DirecTV ne-GPS, izikhulisamsindo ze-audiophile stereo, izinhlelo zezempi (ezifana ne-radar) kanye nezidluliseli zomsakazo ezinamandla aphezulu kakhulu kanye ne-UHF.
NginguJoost Nusselder, umsunguli we-Neaera kanye nomkhangisi wokuqukethwe, ubaba, futhi ngiyathanda ukuzama izinto ezintsha ngesiginci enhliziyweni yesifiso sami, futhi kanye nethimba lami, bengilokhu ngidala izindatshana zebhulogi ezijulile kusukela ngo-2020. ukusiza abafundi abathembekile ngokurekhoda namathiphu esiginci.
