No, no, no. Do not install electrolytics with reverse polarity!
I meant that you should check the negative leads to be sure they are installed correctly.
How about a schematic?

Notice that electrolytics (20) and (42) have their negative leads connected to chassis ground, but not so with electrolytic (44) - its negative lead is connected to B-, not to chassis ground. If you connected its negative lead to chassis ground, your radio will always hum.
Check (44) and get back with us.
