[Amps] [AMPS] How to start?

[Augusto Yipmantin]

Hi all,
 
My name is Augusto, OA4CVT, I am making a 432 mhz cavity using a 4CX250B
tube from EIMAC.
At moment I have an HV power supply with 1700 to 2000 VDC working well,
it was made to drive a 3CX1500A tube for HF.
What I need to make is a 375 VDC regulated power supply for the screen
tube and 5V @4Ah for filament. Some people told me about the IP-32 power
supply for a Heathkit amplifier, but there is not information available
for this device.
May anyone help me to get a schematic for the power supply?
