Stupid mistake: forgot to archive 10.6.5

I was in the process of migrating to a new laptop and distractedly updated both macs to make sure they were on the current version of everything while moving settings/files etc, and I didn't archive 10.6.5 beforehand — and I'm being bitten by the bug with audio filter settings (I use the limiter audio effect extensively as I assemble a lot of stuff quickly from self-shot video).

Does anyone know of a way to download 10.6.5 from somewhere that isn't a cracks site or virus-laden disaster area, or am I stuck recreating any old projects I need to update/build from?
