SKA GB150D now public domain...

Seek and you shall find!
I managed to get ahold of kits for four channels och the GB150.

Now, I built this amp fifteen odd years ago (and sold it) and I remember that I had some serious problems during construction.
The bias, if I remember correctly, went crazy due to to large heatsinks and blew the transistors. I had to replace them and get another pair that I screwed onto the MOSFETs. Something with the temperature. But I can't remember if I replaced or just added these parts.

I also believe that there where some mods we discussed at the forum which is now gone.

So, is there any collected documentation of the early mods?
I have seen some photos but since they are spread out over many years and what seems like different models/versions I thought that I better as here.
