I have in my possession a Sansui Model 370V. There is a hum using the Sansui Model 370V. The wires were connected as follows: 1. Red and Green were connected to the Centre and outer RCA Cable or cable with a screen over the centre cable. 2. Blue and White were connected to the Centre and outer RCA Cable or cable with a screen over the centre cable.
The cable is about a 1.5 metre long connected to the Equaliser Phono input (with a variable volume output). Was there any thing that I did wrong that causes the hum.
