Re: gEDA-user: [OFF] high current amplifier

[Levente Kovacs <leventelist@xxxxxxxxx>]

We want to avoid transformers. The older version of this equippment had the
good old Quad-405 power amplifiers, and transformers at the end. It is so
heave, that one man can hardly lift the unit.

Btw... the same unit must also provide a voltage output up to 300V, but only
100Watts. For that, we'll go for transformer.

And a plus... multiply everything by 3, hence it must be 3 phase...
