00:00:00.439 okay this is my amplifier and I'm going 00:00:06.01900:00:06.029 through replacing the bad caps I'm 00:00:09.95000:00:09.960 looking at these ones down here these 00:00:11.29900:00:11.309 are your big 15 you have and if you can 00:00:14.74900:00:14.759 take a look if you can see right there 00:00:16.70000:00:16.710 or not but you see like corrosion that 00:00:18.59000:00:18.600 is on the end of these caps so that one 00:00:22.27900:00:22.289 and this one here you can see it very 00:00:23.59900:00:23.609 well or not but there is active leaking 00:00:27.00900:00:27.019 going on with this capacitor and this 00:00:31.88000:00:31.890 capacitor and you can even see if you 00:00:33.47000:00:33.480 look down here you can see is down in 00:00:36.17000:00:36.180 the bottom down there it's actually 00:00:37.63900:00:37.649 dripped all over down in there from 00:00:40.01000:00:40.020 these two capacitors because this thing 00:00:41.54000:00:41.550 sits on end so it drips that way so 00:00:44.38900:00:44.399 these are dripping capacitors but yet 00:00:45.97900:00:45.989 when I check these to my ESR meter here 00:00:56.11000:00:56.120 it shows this one is a capacitor a 23:31 00:01:02.00000:01:02.010 UF and ESR of only 0.06 so for the meter 00:01:07.16000:01:07.170 both and I checked the other one as well 00:01:08.63000:01:08.640 for the meter both of these are very 00:01:10.78900:01:10.799 good functioning capacitors but yet 00:01:13.76000:01:13.770 they're both actively leaking so I'll be 00:01:16.55000:01:16.560 ascending to replace and said you only 00:01:17.96000:01:17.970 were gonna buy the meter you would think 00:01:20.21000:01:20.220 these are good capacitors but yet 00:01:21.83000:01:21.840 they're failing but they're still both 00:01:24.28900:01:24.299 well within tolerance because these are 00:01:27.38000:01:27.390 non polarized is the only two non 00:01:31.01000:01:31.020 polarized capacitors on this sh p 3 amp 00:01:35.03000:01:35.040 and after your main non polarized kind 00:01:37.37000:01:37.380 of challenge to be able to replace those 00:01:40.76000:01:40.770 since you can't just go and find another 00:01:42.44000:01:42.450 one of these they don't manufacture 00:01:43.52000:01:43.530 these anymore this is a 1500 us so what 00:01:49.39900:01:49.409 I'm having to do is take and solder 00:01:52.37000:01:52.380 together in parallel sequence but with 00:01:59.12000:01:59.130 the two these are polarized that the 00:02:02.95900:02:02.969 solder negative 2 negative and these are 00:02:09.10000:02:09.110 3300 UF 35 volt so what you do with that 00:02:15.11000:02:15.120 when you put them in parallel like this 00:02:17.75000:02:17.760 is you take it's the exact same 00:02:21.28000:02:21.290 capacitor by the way it cuts it in half 00:02:25.30900:02:25.319 so half of 3300 is 1650 so that's gonna 00:02:32.30000:02:32.310 be fine because we're trying to get it 00:02:33.94900:02:33.959 1500 and then you double the voltage 00:02:36.55900:02:36.569 which is 55 plus 35 is 70 and we're 00:02:42.44000:02:42.450 trying doesn't you know voltage as long 00:02:44.83900:02:44.849 as it's the same voltage or higher and 00:02:47.15000:02:47.160 so our original specifications were for 00:02:51.80000:02:51.810 a 35 volt on 1500 UF so this'll be just 00:03:00.22900:03:00.239 fine so I'm just soldering these 00:03:02.47900:03:02.489 together and so I've got two more I'm 00:03:04.10000:03:04.110 here and I put a little flux on them and 00:03:06.55900:03:06.569 that makes them sexy stick really well 00:03:08.72000:03:08.730 so now I'll be able to solder these two 00:03:11.24000:03:11.250 using my solder our will help plant for 00:03:15.19900:03:15.209 their when you're gonna replace these 00:03:16.69900:03:16.709 two make sure that you keep them non 00:03:19.25000:03:19.260 polarized and don't trust your ESR meter 00:03:23.14900:03:23.159 because in this case they both look good 00:03:26.21000:03:26.220 from the meter standpoint yet they're 00:03:28.36900:03:28.379 both actively leaking Ella Capo's all 00:03:32.39000:03:32.400 right so I've now soldered together 233 00:03:36.74000:03:36.750 UF 35 volt capacitors negative 2 00:03:41.99000:03:42.000 negative and I have hooked them up to my 00:03:43.81900:03:43.829 ESR meter see what happened so 00:03:53.69000:03:53.700 it takes it down truly to a 15:49 where 00:03:57.92000:03:57.930 we're shooting for 1500 so that's 00:03:59.74000:03:59.750 excellent
