Check with Toroid transformers/Noratel for mounting the transformer.

Danne, det funkar bättre med engelska. Om du inte är intresserad av att "utlänningar" hjälper dig så är www.hififorum.nu ett bättre ställe att fråga, indeed english is better if you want help and besides this is an english forum and infact a bit unpolite to the rest of the world.

If you think power losses in dB's it isn't so much. Can you hear it? I know also the feeling of squeezing out as much as you can. I added extra PS in my QRO design.

Danne,
another swedish forum you can consider if you don't master english is www.faktiskt.se.

In Swedish:
Danne om det känns svårt med engelska språket, prova då även www.faktiskt.se, det kommer inte accepteras även av svenskspråkiga att du skriver på svenska då detta forum som är avsedd för alla, vilket innebäratt det skrivs endast på det "internationella språket" engelska iaf på detta forum, hoppas det är ok.

mvh Michael

Let's say that you get 200 W (= 57 V peak at 8 ohms) out if you manage to get almost the same top voltage as the supply voltage, but your design allow you to get only 45 Vpeak, then you'll get 126 Watts out and this give you only 2 dB less output power and also in sound pressure level. 2dB is very little. You hardly hear it in real music. If you increase the level out with only 2 dB, it's very little.

The reason I used higher supply voltage for the driver was only that I was hungry for watts.
