Mark levinson input stage power supply

[montana]

Hi guys
I need your help in order to understand something
I tried to understand the differences between the no 33 and the 33H
And one of the differences is in the voltage regulation circuit that supply the input stage
At the end of the circuit you can see 2 electrolytic capacitors of 100V 330uf while in the 33H there isn't any...
Why is that ???

Thanks for all the replyers

No.336 regulated power supply and No.331 regulated power supply also omit this capacitor.

This capacitor can be installed on the voltage gain board. There is a 150uf capacitor on the voltage gain board of Mark Levinson NO.336

Thank you very much for informing me about this.
The 33H And the 33 as a 330uf 100v capacitor on the voltage gain board.
