Sziasztok!
A TCA530 (csatolmány) egy Grundig R1000 rádióerősítőben lakott, de elhalálozott, ezért nem működik az URH sáv. Forró, és a kimenetén nincs hangolófeszültség.
Ha valakinek lenne elfekvőben (bontott is érdekel), írjon, és megegyezünk.
Ha helyettesítőt tud ajánlani valaki, az is érdekel.
Üdv:
Fülesmester
Sziasztok!
Az InvasionVSH100 erősítő kapcsolási rajzát szeretném megkapni.A tanyán nem találtam.Néhány helyen kijött a működtető füst,és rajz hiányában képtelenség beazonosítani az elégett alkatrészeket.
Kellemes napot mindenkinek!
üdv: Laci
Üdv Mindenkinek!
NAD 3020E típusú erősítőn bekapcsolás után 1-2 másodperccel egy zajhullám fut végig. A zaj minden bekapcsoláskor jelentkezik.
A kisebb elektrolitkondik kapacitása jó, a névlegeshez közeli értékű.
Ettől a zajtól eltekintve az erősítő jól működik.
Mi lehet a gondja?

Hello everybody in Hungary,
I am looking for schematic diagram of portable player THOMSON TM9670.
When I connect an USB drive into the machine, the normal supply voltage 5.5V drops to approx. 2.0V in dependency of each usb drive. The player reports that no usb is connected.
I found out that power supply circuit comes from transistor D882L – from pin No.3 which is base pin. This doesn’t make any sense to me. I would expect it should be connected to collector or emitor pin. Therefore I need schematic diagram or service manual for this player.
Thank you in advance for any help.
Regards,
smith666
