HI,
One of my friend has purchased a Victor (JVC) AX900 amplifier from Japan auction market. But the amplifier is functioning left side but not working right side. someone has attempted to fix it previously and power transistor pins are open form the PCB.I haven't find the original Sanyo IC on the PCB, I assume that the biasing IC "VC5022" is the issue; This IC no longer avalabile in our local market and probably fake IC floating in online market place! In these situations, I think to connect an equivalent IC slot. I have share the schematic which I found in the internet. Does anyone have any experience using the equivalent circuit to resolve this issue? Thanks
