Marcel,

I hesitate to give any advice about a high voltage power supply, because 
of the lethal voltages. You could easily be killed if you do not take 
the proper precautions. Having said that, please be very careful. If you 
open up either the power supply or the RF deck, make sure that the 
capacitors are discharged before touching anything. When the power 
supply control cable is not connected to the RF deck, the primary power 
relay will not energize, so the power supply does not really get turned 
on. So you have not really tested very much of the system by doing this. 
I suggest that you very carefully check that the transformer is wired 
correctly to the power supply, and that the HV shorting interlocks are 
being held open when the cabinet is put back on. Do not open the cabinet 
with the power cord plugged in, and do not plug the power cord in with 
the cabinet cover off.
