[QUOTE="akheathen, post: 7422251, member: 629234"] well, save for a small portion of amps, the boards are not really rigidly attatched to the heat-sink, so vibrations, especially higher frequency, put a strain on all the solder connections. over time, any thing with mass, or rigid vs. flex will develop dry connections, which may also take a long time before you even know that the damage has occured. this is why most older used amps do have dry connections that need soldered to prevent a failed circuit...... i would use rubber grommets on both sides of the mounting feet held by a washer screwed through. and yes, the kac amps are kind of solid in some aspects, and are greatly smd components, but still hold a bunch of bigger caps centermass to the board, and i don't think they are even glued down, or reinforced in any way, just soldered by the legs to the traces..... when you build the box, it would be a good idea to use bracing to the other side directly behind where it will mount.
