stax only uses semiconductors made (diffused) in japan.
just about all stax solid state electrostatic amplifiers use low side npn current sources.
The T2 used a cascode pnp/npn high side current source. But this requires a load current of 12ma or more to work right. And parts that no longer exist.
The only suitable high side current source today that is >700 volts and works at 5ma is made by ixys (littelfuse)
There are no pnp transistors in current production >700v. Which was the only way to do 5ma.
