I have cutted the pcboard..i found that we cannot use L shape adaptor
to high power...so...if this amplifier is able to put out 300 watts (distorted at 2 ohms) you should install your power transistors directly into the main heatsink avoiding L shape adaptor

I am suggesting my people to cut the board (saw) this way
My mistake not to forecast this stuff before.
Since the Supercharged, and them the Dx Blame MKIII and some other models...Dx Blame ST included...i was already cutting this piece of pcboard off...i cannot understand my dumbness.

Very nice Carlos! But Why didn't you put the heat-sink on the other side. I think the way you have it now will not dissipate heat too easily since there is a small thin/short blade holding ALL the transistors. I think it should be better if all transistors are mounted on the bottom (thick side) of the base of heat-sink. I hope I get myself understood...😱

I have tested Lanchile.... this way is a little bit worse
Just a little...but this is a very long story...a video explains this in portuguese only.
Here you have....give a try to see if you understand me:

This way is better to me, then i can install two amplifiers along the enclosure and pump air from the upper case....another long story.

Nice contrast. White and black, the components should be gold 😀

Juanito..... having time, please send me gerbers to my files
This gonna be the standard pcboard layout from now on.
We are reducing the Brazilian layout too...transistors must go directly into the heatsink to increase thermal transference.
That lost pcboard the brazilian complained, have arrived from Puerto Rico, 186 days latter...but arrived...the man is transfering the money to your account.

Yes....may sound metalic
At the end it is a steel Super A.
This one (picture) may be the heatsinker..... all heatsink... a high power prototype... plus and minus 90 volts.... or aluminum

Now that we have made the board even smaller, now we have copper track reinforcements for better current travel into important areas, I hope you guys like this 😀 .
