[Amps] Some PS questions

[Vic K2VCO]

1) I'm building an amplifier with a separate power supply with the negative output 
isolated from ground to allow for plate current metering. The meter will be located in the 
RF unit. Where should the safety resistor between B- and ground be located? In the power 
supply or in the amp?

2) What's the current thinking about shunt capacitors across rectifiers? I am going to use 
a bridge with 5 6A10's in each leg. They are all from the same batch (at least, they came 
on the same tape). Do they need capacitors? I will have MOVs in the primary circuit.
