I agree. Get rid of them.

I had a European set that used this. When I received the set it only had one and it was fried. It was a later date code than the rest of the set so it had been replaced once already. And the transformer secondary was fried on the side where the cap was.

Not sure what the motive was. If it was rf bypassing it would normally be placed on the primary side. All I could think of is that it might be intended to reduce spikes coming from the transformer in the case of fluctuating or nasty power. A cap seems like an unnecessary risk at that point in the circuit.
