Hiya, am seeking a Penta amplifier circuit diagram. I have found a few on the web but this request relates to the input board. Early Penta Mark1s used an input board numbered 8002831 and used 6 transistors. my board is numbered 8002831E and looks similar - but in addition to TR1 to TR6 I have TR8 Tr9 TR10 TR16 TR16 on the circuit board. As its this board that is not working i'm quite keen to get hold of the right circuit diagram. The case says Penta 6602. Any help greatly appreciated. Happy New Year
Ezt hangkártyát vettem alaplapi helyett (hibás lett az alaplapi )
Sajna minden kimenete ( fejhallgató, 5.1 ( 3db) jack) sokkal halkabb az alaplapinál. Próbáltam valami erősítéssel, de minden kimenetre nem tehetek külön opampot.
Van valakinek ötlete mit lehetne csinálni?
A "kártya" szépen működik, valszleg nem hibás, de hátha...
Hi.
A fenti kétkazettás deck mindent csinál csak visszafelé lejátszáskor kb 2 mp mulva leáll és f03 hibát ir ki decsak az aktuális lejátszonál,a másik müködik szépen.
Minkét oldali mechanikánál ezt teszi.
A bal oldalin cseréltem szijat,nyomogörgöt és azt gondoltam valamit nem jol raktam össze,de a jobb oldalihoz még nem nyultam és az is igy tesz.
Utánaolvastam a googli barátunknál,de érdemi segitséget nem találtam.
Volt olyan külhoni aki a forgásérzékelö tisztitását javasolta,megtettem,maradt a hiba.
Volt aki a táp javitását javasolta,megtettem,maradt a hiba.
Megakadtam.....
Talán még az optos forgás ellenörzö rész elektronikus átnézését eröltetem,hátha ott lenne a bibi.
Ha lenne valakinek ötlete, tapasztalata azt megköszönném.
Üdv.egon
