Lot of 12 High Voltage 2400 uF 450 vdc Capacitors
eBay item #330298178472 provides 243 joules in each capacitor. I purchased twenty-four capacitors (two lots) for a total of 5,832 joules. I will keep several as spares. I will use much less than the rated voltage to maximize their life span.
I paid $58 + $62.98 shipping for a total of $120.98 USD.
The capacitor is Philips part number 3186GH242T450AJA2 with this datasheet.
eBay item 200280433943 is for two 120vac solenoids: Gaurdian 3HD-I-120A is a 120vac intermittent-duty actuator. It is interesting to note they contain, under their white-tape wrapping, a small bridge rectifier and filter capacitor.
I paid $15.22 + $2.15 shipping for a total of $17.37.
