Hi
Please advice a simple bjt high voltage amplifier
output : 200~400vpp
in:1.5vpp
BW:1khz
output current_MAX:1mA

Thanks!
 

Have a look at the MSK130 high voltage opamp:
**broken link removed**
Its max supply is around 400V so it will be pretty close to what you need.
Altenatively, you can build a similar amplifier using its equivalent schematic ..

Thanks!
But I need only the simplest amplifier like one or two discreat BJT.
 

Have a look at the AB-class output-stage video amplifier. If proper HV transistors are used, you can possibly go as high as 400V ..
Regards,
IanP
