Szép napot mindenkinek ! Egy gyári Wolswagen hangfal, /aktiv/ bekötésére lenne szükségem. Ez van rajta, WW ISOPHON 867 035 403 . Úgy kaptam , elég izmos cuccnak néz ki ,szétszedni sem lehet, csak ha roncsolom . Infót nem igen találtam róla, egy kis HELP jól jönne ! Előre is köszönöm .
Sziasztok.
A fent említett rádióerősítőt generálozom de lenne vele 3 problémám.
1: Raktam bele egy koppanásgátlót ami frankón működik is, de amikor a relé behúz (kb: 2mp után) akkor is koppanik a hangszóró.
2: Meg lehet-e valahogy szüntetni a sustorgó hangot a kimeneten?
3 Egészséges-e ez hogy a kimeneten terhelés nélkül 900mV-ot mérek?
A végfok kivan szerelve és úgy próbálom, úgyhogy a előerősítő + a szabályzó modul nem befolyásolja.
A 2200uF/25V-os kondikat már kicseréltem mert már eléggé ratyi állapotban voltak.
Kimeneten BD249, BD250 - es pár van.
Az infókat előre is köszi.
Trying to troubleshoot a issue with this radio and there are some SM / schematics on some websites,
but they are slightly different than this one.
Would anyone know a place to look where there are some Grundig people familiar with the products?

Sziasztok. Vásároltam két db hangszórót amiről csak annyit tudok, hogy 4.8 ohmosak, átmérőjük 31.3cm, valamint két felirat található csak rajta: a mágnesen A/67, a kosáron 11-74. Ismeri-e őket valaki? Legfőképp a terhelhetőségére lennék kíváncsi. A válaszokat előre is köszönöm. Üdv. Roli
