Fett det där med, misstänker att vi har samma kondingar?!

How are the plates connected to each other?I think I see pipes or something perpendicular.I don't know how efficient the coupling between plates is so as maximise heat transfer.I think parallel 10mm bars between plates would be better with more surface area.It seems that paralleling plates would trap heat in the space between them.
But , hey, as long as it is cool enough and you can hear your your music who cares? That's "cool" for me.

The big plates are connected with 3 paralell plates, and the paralell-plates are 50x300x8. I don´t know if you got any wiser of this, but I try to explain as good as I can.

Now I have mesured the bias, and it´s aprox 7amp each side.

Oh well,

that´s quite a lot

With this much bias you can probably do without any ac-current gain.

55V x 2 x 7 x 2 = 1540 watts for the complete amp

Are you shure it´s 7A

I just mesured and found out that the voltage is 45volts, and it´s 3,5amps x2 for each channel. It makes it a total of 620 wattts. The 55volts was mesured non loaded.
