Update Ferranti R4 en R4A

Full Wave rectifier
Vf = 4.0 Volts Directly heated
If = 2.5 Amps
Va-a = 350-0-350 Volts (R.M.S)
Max Rectified Current = 120mA
Max Reservoir Capacitor = 32uF
Minimum Anode Series Resistance = 120 ohms
Base = B4

Type R4A is the same except for:
Va-a = 500-0-500 Volts (R.M.S)
Minimum Anode Series Resistance = 100 ohms
