Just built an amp that used some Panasonic snap in's for the mains filter and it turned out killer! If you're careful measuring and drilling they can work great for an eyelet board. It was these http://www.triodeelectronics.com/100uf400sc.html Picked some up while ordering some iron and I was pleasantly surprised. I think I've seen some recent SLO's using these, could be wrong….I'm getting old
I got some 30mm clamps just gonna mount them like regular capcans . I'm not fond of glueing caps and stuff like that. Or mounting big radial caps on a board. I try to build stuff with being dropped in mind
