National NC-100XA AVC-circuit (Techniek Radio/TV)
Deze ontvanger blijft problemen geven. In de stand MVC kan ik prima de versterking van de RF- en de MF-trappen regelen, maar in de stand AVC komt er geen signaal meer.
Ik zou op punt A van de schakeling, bij geen antennesignaal, een spanning van ca. 0 Volt moeten hebben en bij meer signaal een negatievere waarde. Ik meet echter steeds ca. -40 Volt op punt A.
Ik heb de schakelaar op MVC gezet en de verbinding naar de anode losgekoppeld, dus wel signaal op het stuurrooster, maar nog steeds - 40 V op de anode. Ik begrijp er niets meer van.
