Question about Onkyo Audio Players & Recorders
Since the input of the phono is of very high impedance and of high gain it is important that the signal is fully protected from any possible induced stray signals of AC or EMI.
Hence the cables must be firmly in place to the Amplifier til there is no hum. If there is hum and the hum reduces as you touch the output pins the outer ground pins of RCA, then reverse the power plug of the turntable. If this wont improve then a ground must be connected externally.
Hoever if none of these prove it is possible that the shield to the stylus is faulty, the lines of the connecting output is faulty.
Make that the phono of the amplifier does not have any hum with the input removed. If so the preamp has a faulty.
