okay this is my amplifier and I'm going
00:00:06.019 00:00:06.029 through replacing the bad caps I'm
00:00:09.950 00:00:09.960 looking at these ones down here these
00:00:11.299 00:00:11.309 are your big 15 you have and if you can
00:00:14.749 00:00:14.759 take a look if you can see right there
00:00:16.700 00:00:16.710 or not but you see like corrosion that
00:00:18.590 00:00:18.600 is on the end of these caps so that one
00:00:22.279 00:00:22.289 and this one here you can see it very
00:00:23.599 00:00:23.609 well or not but there is active leaking
00:00:27.009 00:00:27.019 going on with this capacitor and this
00:00:31.880 00:00:31.890 capacitor and you can even see if you
00:00:33.470 00:00:33.480 look down here you can see is down in
00:00:36.170 00:00:36.180 the bottom down there it's actually
00:00:37.639 00:00:37.649 dripped all over down in there from
00:00:40.010 00:00:40.020 these two capacitors because this thing
00:00:41.540 00:00:41.550 sits on end so it drips that way so
00:00:44.389 00:00:44.399 these are dripping capacitors but yet
00:00:45.979 00:00:45.989 when I check these to my ESR meter here
00:00:56.110 00:00:56.120 it shows this one is a capacitor a 23:31
00:01:02.000 00:01:02.010 UF and ESR of only 0.06 so for the meter
00:01:07.160 00:01:07.170 both and I checked the other one as well
00:01:08.630 00:01:08.640 for the meter both of these are very
00:01:10.789 00:01:10.799 good functioning capacitors but yet
00:01:13.760 00:01:13.770 they're both actively leaking so I'll be
00:01:16.550 00:01:16.560 ascending to replace and said you only
00:01:17.960 00:01:17.970 were gonna buy the meter you would think
00:01:20.210 00:01:20.220 these are good capacitors but yet
00:01:21.830 00:01:21.840 they're failing but they're still both
00:01:24.289 00:01:24.299 well within tolerance because these are
00:01:27.380 00:01:27.390 non polarized is the only two non
00:01:31.010 00:01:31.020 polarized capacitors on this sh p 3 amp
00:01:35.030 00:01:35.040 and after your main non polarized kind
00:01:37.370 00:01:37.380 of challenge to be able to replace those
00:01:40.760 00:01:40.770 since you can't just go and find another
00:01:42.440 00:01:42.450 one of these they don't manufacture
00:01:43.520 00:01:43.530 these anymore this is a 1500 us so what
00:01:49.399 00:01:49.409 I'm having to do is take and solder
00:01:52.370 00:01:52.380 together in parallel sequence but with
00:01:59.120 00:01:59.130 the two these are polarized that the
00:02:02.959 00:02:02.969 solder negative 2 negative and these are
00:02:09.100 00:02:09.110 3300 UF 35 volt so what you do with that
00:02:15.110 00:02:15.120 when you put them in parallel like this
00:02:17.750 00:02:17.760 is you take it's the exact same
00:02:21.280 00:02:21.290 capacitor by the way it cuts it in half
00:02:25.309 00:02:25.319 so half of 3300 is 1650 so that's gonna
00:02:32.300 00:02:32.310 be fine because we're trying to get it
00:02:33.949 00:02:33.959 1500 and then you double the voltage
00:02:36.559 00:02:36.569 which is 55 plus 35 is 70 and we're
00:02:42.440 00:02:42.450 trying doesn't you know voltage as long
00:02:44.839 00:02:44.849 as it's the same voltage or higher and
00:02:47.150 00:02:47.160 so our original specifications were for
00:02:51.800 00:02:51.810 a 35 volt on 1500 UF so this'll be just
00:03:00.229 00:03:00.239 fine so I'm just soldering these
00:03:02.479 00:03:02.489 together and so I've got two more I'm
00:03:04.100 00:03:04.110 here and I put a little flux on them and
00:03:06.559 00:03:06.569 that makes them sexy stick really well
00:03:08.720 00:03:08.730 so now I'll be able to solder these two
00:03:11.240 00:03:11.250 using my solder our will help plant for
00:03:15.199 00:03:15.209 their when you're gonna replace these
00:03:16.699 00:03:16.709 two make sure that you keep them non
00:03:19.250 00:03:19.260 polarized and don't trust your ESR meter
00:03:23.149 00:03:23.159 because in this case they both look good
00:03:26.210 00:03:26.220 from the meter standpoint yet they're
00:03:28.369 00:03:28.379 both actively leaking Ella Capo's all
00:03:32.390 00:03:32.400 right so I've now soldered together 233
00:03:36.740 00:03:36.750 UF 35 volt capacitors negative 2
00:03:41.990 00:03:42.000 negative and I have hooked them up to my
00:03:43.819 00:03:43.829 ESR meter see what happened so
00:03:53.690 00:03:53.700 it takes it down truly to a 15:49 where
00:03:57.920 00:03:57.930 we're shooting for 1500 so that's
00:03:59.740 00:03:59.750 excellent
