cap multiplier at 33V input

[audio1]

Hi. I've been using the Allo capacitance multiplier with the Allo 19V SMPS, to feed a TPA3118 amplifier,
but now I would like to use the cap multiplier with a 32V SMPS, into a TPA3250 amplifier - and this is at the upper limit of the cap multiplier's published specifications.
Will the cap multiplier be OK at 32V ... or if the SMPS output is not perfect - even 33 or 34V?
Or is there some component(s) on the board that I could replace to keep everything safe? Maybe just use a bigger heatsink on the MOSFET?
I intend to set the board to drop 0.3V.
Thanks.

HI Audio1

 

 it should work. Dont go over 34V. No need for higher heatsink since only thing that matters is voltage dropout. 0.3V wont even make the heatsink warm..

Many thanks.
