Is this better or should I order the 86/82 type?
These questions may seem naive but the terminology in electronics is different in Greek language and sometimes makes it difficult to find the right part, even if it is something simple!

These look suspiciously close to the ones I am using on the ClassA's including the F4 balanced monos - due to their excellent heat transfer, however I am using these with heat paste! It is ceramic discs, they are flat - and they are brittle, so if the heat sink isn't perfectly flat they might either break or not get a good thermal contact with a nice thin layer of paste. That said I am very pleased with the performance.
