1. [Amps] Date Code Samsung 120 MFD 450 Volt Capacitors? (score: 1): Author: "qrv@kd4e.com" <qrv@kd4e.com>; Date: Mon, 11 May 2015 09:40:24 -0400; Would these caps be safe to use in an amp PS? Samsung 120 mfd at 450 volt 105c Would this # EIAJD0160 reveal the date code? Or best not to mess with anything below 500v?

I'm still trying to sort the alphanumeric label EIAJD0160: EIA = military contract? J = ?? D = ?? 01 = 2001? 60 = ?? If 2001 they are already 14 years old - perhaps not a good choice; /archives//html/Amps/2015-05/msg00106.html (9,146 bytes)

(score: 1): Author: Boye Christensen <oz7c@cool.dk>; Date: Mon, 11 May 2015 21:47:24 +0200; Hi If they are old make an EXT. circuit with soft start to test each, e.g a diode with 100 kOhm in series. Use a DMM to measure time /voltage and calculate capacitance. 230 VAC to a diode gives app.; /archives//html/Amps/2015-05/msg00107.html (9,493 bytes)

Just put'em in, turn'em on and wait. You'll soon know for sure, if they are any good. In other words, 95% of the population would simply use them without a second thought.
