Davecv41 Posted May 7, 2021 Share Posted May 7, 2021 I kept the old Aerovox, Sprague, and Astron metal capacitors when I updated them in my Khorn's type A crossovers a few years ago. The recent availability of Klipsch approved replacement caps thru JEM got me thinking about keeping the crossovers original, by removing the old capacitor's guts and restuffing them with new plastic caps. Has anyone ever tried this with a square metal capacitor? I've done it on old radios before, but a Gaggle search only comes up with doing it to round electrolytics. Any idea what's inside these square cans? Quote Link to comment Share on other sites More sharing options...
KT88 Posted May 7, 2021 Share Posted May 7, 2021 Others may know better but there is probably nothing really healthy inside those old caps regarding dangerous PCB. Quote Link to comment Share on other sites More sharing options...
avguytx Posted May 7, 2021 Share Posted May 7, 2021 I would almost doubt any new capacitors are going to fit inside those old cans given how the shapes are different. But who knows... Quote Link to comment Share on other sites More sharing options...

But who knows... The new ones are pretty small but I'd never pull the old caps apart. There's nasty stuff in there. Quote Link to comment Share on other sites More sharing options...
OO1 Posted May 7, 2021 Share Posted May 7, 2021 some oil filled type capacitors used PCB's as a coolant prior to 1979 -IF manufactured after 1979 they may be stamped "NO PCBs" on its casing. These are filled with oil which does not contain PCBs - Quote Link to comment Share on other sites More sharing options...
