Found some 20mF 450V caps on EBay in USA
« on: July 17, 2020, 07:02:36 AM »
Not my listing, but I just bought some of these large 20mF (20,000uF) 450V electrolytic capacitors:
https://www.ebay.com/itm/United-Chemi-Con-Electrolytic-Capacitor-20000uF-450V-New-Open-Box-Reformed/401984486380?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

They look good in bench-testing, 18mF measured with 4-5 milliohms ESR in the 10kHz-100kHz range.  (Tested with a square current pulse, not sine-wave AC.)  Do be careful with these or any such large caps.  It appears I've caused myself some permanent hearing loss by a single incident of accidentally shorting one of these when charged to ~400V . :(
