IFR513 headphone amp channel mismatch
I have a headphone amp based on the IFR513 MOSFET which has a noticeable volume difference between the L + R channel outputs. All the resistors have been checked and measured to ensure a close match. All things being equal, could one or both of the MOSFET's be at fault?
Also, do MOSFET's of the same type differ greatly in output?
I have the amp in bits at the moment (re-wiring the passive pre side of it). Is it worth ordering some more MOSFETS, or would it be worth adding trim pots in the bias cct?
