A 50k bleeder on a 275V B+ is going to shunt over 5mA to ground, and dissipate over 1.5W. A 270k 1W resistor is sufficient, in my experience.Regarding your hum, it's the nature of this topology to be sensitive to hum on the B+ rail. I guess you've nailed it down with all that capacitance, but a filter choke is really called for in this style of amp.
