Thanks for your answer!
Yes, my amp is Destiny 1, but I can't see in the photos if these transistors are placed in the heatsinks or they pass through the heatsink and then they are pinned to it by the plastic clamps.
I'm not sure if they are placed in the right spot in my amp.
It was old stock in the shop, it has been given for demo, etc. and I'm not sure if someone didn't make a mess inside the amp meanwhile.
Best regards!
