[Amps] Some PS questions

[Glen Zook]

I put them in the power supply.  Also, remember, in grounded grid, you will measure the grid current using this resistor as a shunt.  In a grounded grid power supply you have to put the shunt between the capacitor/bleeder stack and the B- to measure plate current.

Most modern designs don't use capacitors anymore.  I don't think they will hurt anything.

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.
