    Hi Name is Dwayne (ve6qx)                            
 I recently changed out the electrolitic caps in my 3800 volt power supply. 
    from 10 210 Mfd at 450 volts to 10  530Mfd at 450 volts per cap. I did this 
    thinking that I would lessen the decay of the voltage when the amp is 
    keyed..  The power supply is a voltage doubler..
      But I'am thinking perhaps all I did was provide to much capacitance for 
    the capability of the transformer..  Perhaps this is more stress on the 
    trnasformer.???   All I have noticed is a longer decay time for the voltage 
    to return to zero when shutting down the amp.(makes sence,more capacitance) 
    Other then that it works fine.. Thanks and maybe someone has a explanation of what's going on cause of this change in cap..
