    Cap suggestion please help!

    And now for something completely different...

    I am rebuilding some speaker crossovers for some vintage ADS speakers and am wondering if anyone can track down the specs of the original caps, I believe they are both non polarized..

    1) Nippon-chemicon Ce02P BP 100v33uf
    2)Nippon- chemicon Ce04P BP 100v130uf

    Anyways, I am terrified that the sound will change if I choose an unsuitable cap... I want to keep the specs as close to original as possible...and I've heard the ESR rating affects the sound. I appreciate any advice or guidance,

    Thanks in advance,

    Mike

      In most all brands 'BP' indicates Bi-Polar [not polarized].
      If so, the caps won't be marked for plus and minus. [No side stripe. No + or - symbols.]
      .
      If that's what they are the replacement series from Chemicon are:
      SME-BP [85°C]
      KME-BP [105°C]

          Appears to be the case.

              I was wondering what happened to initiate the rebuild? ADS's are great, with robust crossovers and rubber surrounds, so was there an issue with overdriving them?

                  Not all bipolar/non-polarised capacitors are created equal.
                  Some are only designed for small signal applications, or horizontal deflection applications, or speaker crossover applications.
                  My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

                      If there is no evidence that the original caps are bad, why change them? You will not get "better" performance unless the originals are leaking or lost their value. There's no magic here and nothing to be terrified about. It is much more likely that your drivers need attention - have a look at the surrounds.
                      Is it plugged in?

                          How can I test non-polarized capacitor?
                          by chth96
                          I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
                          I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

                          And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
                          I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...

                          by eryjus
                          Hello,

                          First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                          I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                          I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                          ...

                          i think i accidently ordered non-polarized 10uf caps for my original xbox. will this cause a problem?
                          by bulkchart32
                          i ordered a lot of caps from digikey to repair my xboxs. one thing i ordered was 50NXA10MEFC5X11-ND caps and i think they are not polarized. will this cause any kind of a problem? i really don't want to order new caps just because of this.

                          How to read inductor specs?
                          by badcap111
                          I have a broken samsung galaxy s10 with missing inductor. I want to replace the missing inductor and I have found some vendors. But I don't understand how to read the specifications of the inductor. The specs are:

                          INDUCTOR-SMD;470NH,20%,2520,T0.8,0.029OH

                          I understand that the inductor is 470 nH with 20% margin, and the size is 2520 or 1008 (imperial measure), but what do T0.8,0.0290OH mean? I can't find any explanation on the web.

                          Unknown diode specs V6 18
                          by badcappo
                          Hi there, looking for a compatible replacement for a diode type labelled "V6 18" from a dead Panasonic plasma TV power source. Possibly a V6 600 volts diode as seen here: https://electronics.stackexchange.co...nt-diode-v6-88 ?
                          Thank you ...
