Sziasztok!
A címbeli antennaerősítőben elégett az LM2594N-12 táp IC. Kérdésem, hogy hol lehet beszerezni vagy mivel lehet helyettesíteni. Ez egy DIP8 tokos 12V 0,5A-os step-down kontroller, ami 24V dc-ből állítja elő a 12V-ot.
Esetleg ha lenne hozzá kapcsolási rajz nem lenne hátrány, mert a panel is megégett a környékén.
Köszi.
Sziasztok!
Mint láthatjátok, elég ramaty, plexi nincs, ha volt egyáltalán... Az egész lemezjátszókar szétesve, tű nincs...
Míg rá nem kérdek nem bontottam, gondoltam megkérdem van-e értelme foglalatoskodni vele :)
Üdv:
Pityesz
Tiszteletem!
A fent nevezett erősítőben zárlatos lett pár db dióda ,ami oa90 germánium.(d308,d302)
Kérdésem az lenne hogy mivel válthatnám ki? Pl 4148?
Üdv:Imre
Sziasztok!
Nem szoktam erősítőket javítani,de ez egy haver gépe.
A baloldali front végfok ment zárlatba.Minden tranyó beszerezhető jó áron,de a 2sa 1770-et aranyáron mérik siniék.Ha valaki tudna normális pénzért nagyon megköszönném.
