BG141341217 i tested with 24-0-24v, 300VA and it worked fine. Then I changed to 30-0-30v, 200VA and it sounds louder and bass is deeper. It seems that voltage is important when it comes to deep bass, not the VA . With a ne5532 tone board, it always sounds transparent, no metter what voltage.

Q: Essa placa amplificadora funciona em 127 ou 220v e em que frequencia?

BG141341217 It does not work in neither 127 or 220v. You need a dual toroidal transformer which provides any of the following voltages: 24-0-24, 28-0-28, 30-0-30, 32-0-32.
