Hiraga Le Monstre 2024

Well, the standard solution, as published by Hiraga, uses a transformer and rectifiers etc. to charge up the caps first.

Probably slightly higher voltage than the batteries.
Switching then takes place across a very small voltage difference.

I have already explained why we don't want to do that.
So we'll still need to have inrush control.

why caps can't be permanently connected to the battery?
charge the caps with a resistor only once then connect permanently to the batteries,
use a switch after the caps to power on or off the amp

 

[EUVL]

If I want a cap in addition to a battery, I want it close to the amp, with short, non-inductive connecting cables.
Not next to the battery.

A switch after the caps but close to the amp can only be a relay or MOSFET switch.
(We have separate caps for each channel.)
Can be done, if necessary.

yes then batteries outside hone, fuse, then cables to the amps where caps are located (cables will do the R of RC filter) then short leads with relay to feed the amp

 

[EUVL]

I prefer to have the components inside the amp de-energised when I switch off.
Batteries can be remote, and can have additional switches on its terminals, like in cars.


Just me,
Patrick
