Hello Chas,
So first all the radio works just fine using he original vibrator.
Far as that "panasonic brand 6800pf or .0068ufd metal film 1.6k v PP .
Part no. ECW-HA3C682H"
So you are saying this capacitor is not rated to use as a buffer capacitor ?
I contacted the guy from the electronic vibrator board he told me to try taking out the audio preamp tube to see if the noise was generated in the front end of the radio and it is still the same so it is in the poweramp section .
I will put the shield over the poweramp board and see if that helps .

my next step is to try 

to "bridge" the electrolytics with mylar or ceramic caps, as electrolytic caps are not necessarily good at filtering out high frequency noise.

Sincerely Richard
P.S. I also replaced the cloth wire power wire and lamp wire plus added a fuse holder .
