Sziasztok !
Annyi a rövid kérdésem hogy ha nem kötök hozzá CD-tárat, a csati tud fogadni külső audio jelet?
Sziasztok! Vásároltam egy használt Dap DCX-24 rendszerprocesszort. Van rajta RS232 port, de sajnos a szoftvere nincs meg és már fél napja túrom a netet, de sehol nem találok hozzávalót, csak az újabb szériás DCP sorozatét találtam meg, de az csak az usb-s modelleket viszi. Valaki tud-e ebben segíteni? Kb 2006-2007-ben gyártott eszközről van szó és nem túl elterjedt, vélhetően ezért nem találok sehol semmit. Annyit sikerült a manualból kihámozni, hogy "DCXSetup_V13.exe" lenne a fájl neve, amire szükségem lenne.
Sziasztok!
Ezzel az erősítővel van gondom, most került vissza hogy elugrott az egyik oldala, át mérve minden rendben találtam, kivéve a két végfok tranyót az egyik oldalon. Csere után járattam, és fél óra után pattanás és hang elment. Megint szétszed, átmér, hibás megint a két tranzisztor ( Q508, Q509 ) mást megint nem találtam ellenállások jók, a többi tranzisztorok is jók, most szól de nem merem próbálni. Mi lehet a gond?
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
