Default SHUNT REG Help needed

Hey all.

I have seen LCAudio 10V shunt regulator with these specifications:

Uout = 10V
0.01ohm from DC to 10Mhz.

I want to make a Shunt reg with a higher voltage (20V) and with transistors instead of BFR92 and BFT92.

The Questen is:

How do you calculate the regulators working frequency?

What component in the circuit limits the working frequncy to 10Mhz?

What if I Change BFR92 with 2SC2240, does anyone then know how to calculate the working frequency?

Best regards
From Denmark
