Evo kako sam koristio 4049 valda ce ti biti nesto ovo od koristi , e sad zavisi sta se tebi  od njega trazi u toj semi ??? dali ovakva veza ili ???.

Plus tebi na semi nigde nije ucrtano napajanje tj nozica 1 za to kolo , dok ova 3 voda sto idu prema masi su ti ustvari jedna nozica i to 8ma

Zanimljiv video, obilazak starog, verovatno prvog takve vrste predajnika od 500kW sagradjenog 1938 godine tj tad je pusten u upotrebu, da vidite kako izgleda AUDIO POJACAVAC od skoro 200kW, modulacioni transformator isto te neke snage, grejanje cevki vuce 3000-4000A, kompletna shema predajnika staje na jedan list A3 papira (to su 3 zgrade sa podrumima + bazen), i tako dalje, gomila interesatnih stvari Smile

30. 12. 1976. Pušten u rad predajnik Radio Beograda, snage 2 000 KW, odobren na Međunarodnoj konferenciji za raspodelu kanala na području srednjih talasa. Bio je to jedan od najsnažnijih predajnika u Evropi.
