Might be better using those to power an Aleph Mini. Boards are available for CHEAP from chipamp.com at the bottom of the order page.

It reduces hi frequency line noise, both incoming and outgoing.

burning trafo

bobodioulasso · 31st July 2009, 10:41 AM

Did you burn it trying with F5?
No mains fuse?

I joke

I mean that trafo will run hotter

any one can report what gain in sound with dual mono psu ??

or at last one trafo and dual mono cap/diode......

I reckon a pair of monoblocks always sounds better than the same amplifiers built into stereo amplifier case irrespective of whether one or two transformers are used to power the two channel amplifier.

Are you saying that separate cases make a larger difference than using separate transformers?
