Előre is köszönöm Üdv:Mitu

Want to share: Have downloaded the schematics from this forum to help repair the amplifier of a friend. Turned out that Sony decided to route the earth through the chassis, even the earth between the various supplies. When one takes the main board out of the chassis and switches the amp on, there are up to 20 volts difference between the eart (and hence reference) of the pre-amps and the main amps. Luckily the amp goes into protection but from a design point of view it is not nice to rely on screws and aluminum face plates to conduct up to 0.2 amps of current from one supply to another. What I did is solder wires to every eart point and connected them on the main board to make it stand alone and not rely on conducting current through the chassis anymore. Bad design, simple repair but took some digging in the schematics to find out what exactly was going on!

Hello I’m new here I know there is a SMPS schematic on this website but I need the full schematic for the hole machine or a service manual or both for the Camco Audio Vortex 6 PA Amplifier if anyone has a copy can you please upload it I’ve tried asking for it in the wanted section of the website but since someone uploaded just the SMPS now it wont let me ask for the full machine schematic or service manual please help thank you 

Üdv mindenkinek! Ehhez a kis Sony erősítőhöz keresnék Service Manualt,vagy egyéb bármilyen doksit.
