Dear Halcro: Oscilations on SS electronics almost always occur and can damage the unit. Things are that several designs were not full tested to be aware on " problems " through the designed circuits.
As Almarg posted " something " exited that kind of circuit oscilations and then the damge in the unit.
Now, a mute function is to mute the output level it does not matters at which position/level the volume is. I can't be sure but maybe the " culprit " is that your unit design has no protection about or was designed not full tested for this kind of problems. An SS design is a lot lot more complex than a tube one and the SS designs are a lot "weak " than the tube ones.
In the other side: do you already tested to put the stylus in your Victor when the Victor is not connected to the wall electric source?, try it and share what happened.
Regards and enjoy the music,
R.
