18v rectification ??

[onis_uk]

ive got two mono amp boards that require +25V@5A each.
im going to get a transformer that throws out 2x18V on the secondary's

will this circuit do what i need as far as rectification to 25Vdc ?

Does your amp need a 25V dc supply or a + and - 25vdc supply ?

The kit you show is for a + and - supply not a single supply.

i need +25vdc for both amps i think ?!

I'm going to get a 225VA one ==> 0225218 : Chassis mounting toroidal transformers for sale online

so I need two modules ?!?! they way i read it is that the module can take + or - up to 60V ?, dual rail ?!?! (up to 2x42V transformers) this is going to get expensive if i have to get 2 as they are €ur64.00 each !!!!!!!
