1. Things you need to know about the new ‘Conversations’ PM system:

    a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.

    b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.

    What are the bits mounted on heat sinks?

    Resistors most likely

    Do they really get so hot? And if so, why not overspecify instead?

    Crossover resistors can get extremely hot indeed.

    bigger resistors often mean increased inductance, so adding a heat sink gives you the power handling without the added z.
