Hello and thanks for taking the time to read and respond. I am in the process of restoring an old RF amp I recently changed the caps in the filter section and now replaced the HV diodes in the power suppy from single 3kv the a string on 1n4007. I have read that to equlize the voltage drop accross the diodes I need to add a cap and resistor in paralle accross each diode in series. My question is does anybody have the formula for finding the value of the resistor needed. Thanks
