@mcdanlj I'd read that spiral flute taps are weaker and more likely to break for small taps, so I haven't tried them yet. Thanks for the pointers!

Metalwork for the linear amp is going GREAT. First I drilled the wrong hole sizes for the heat sink, then broke two 4-40 taps. Will figure out how to extract these then try a thread forming tap instead of a cutting tap.

Anyway, something good -- found a building full of electronics stores in Singapore a couple of weeks ago. So much stuff you don't see on shelves in the US or Australia now, all kinds of niches.

Location is Sim Lim Tower.
