which amp schematic for my speakers?

joda · 19th January 2011, 05:24 PM

hi fellow DIYers,
I have at home a couple of exceptional power supply
double C-core transformers 650VA 28-0-28 volt AC, four 100mH inductors for DC 5A.
two alluminium case whit heatsinks 400W. I would like to build two monoblocks with high power bipolar transistors (or mosfets

.....), with balanced input.
My speakers are Vertigo Plus project whit Scan Speak illuminator. Impedance is only 3ohm.
suggest a schematic or a module with PCB amp top level, thanks!

Thanks to all
best regards

There are many schematics available on the forum. These transformers must be huge? Keep in mind that when the amp is idle these transformers still draw a lot of current. Monoblocks would be a good choice though! Personally I would go for SE MOSFET driven by an opamp.

with those parts, I'd be building an aleph 60.
