give 2x50v take 400w give'n take simply.
I'm using this pré amplifier http://construyasuvideorockola.com/d_premic.php with a little modification, i just ommited the mic input on the circuit, I tried using TL072 and NE5532, its connected to my computer via Maudio Delta, the PSU for the preamplifier is separeted, +15 0 -15 regulated with LM7815 and LM7915. The main power supply is that toroid transformer from the last post with 20000uf per rail, and rectified with MUR860 diodes. I have checked the cables and all the connections and i don´t know why i still have that noise. I´m considering changing the TIPS. The use for this is 2 PA Boxes with each one with 1 15'Woofer, 100w driver and 50w tweeter (all from Selenium).
Thanks for your attention
