    Need help with 4700uf 25v replacement in subwoofer

    Bought a cheap sub on marketplace for $20. Has two 4700uf 25v Jun Fu 85c rated caps. I've found several replacements for around $1 or 2 but what ripple current rating should I shoot for minimum? Also they have to be 16mm wide and a max of 30mm tall, lead spacing is 7.5mm and they are through hole.

    I am about to buy these just because they're cheap and 105c rated

    Edit: add some bad 22uf 25v Jun Fu's to the list as well

      i wouldnt bother,
      your not hitting the caps with high frequency's

      if you do replace them you need high ripple current handling.

          Please help, subwoofer connected to tv, read description below
          by rustinjust
          I've got a subwoofer that I've had for nearly 20 years, it did come with a basic remote which I've lost. It's a generic make of subwoofer, I can't see a brand sticker on it. It comes with 2 speakers.

          Question recently I've connected it up to my tv which has greatly improved the sound on my tv, however I'd like to be able to mute the subwoofer when ads come on or just mute it when the phone rings etc. I tried using a cheap all in one tv remote on the subwoofer and the volume button would only work to increase volume but not turn it down or mute it

          Is there a way of...

          Repairing a Music Store Professional GO! SUB 18A
          by h0m3w0rk
          Hello everyone,

          I'm working on repairing a Music Store Professional GO! SUB 18A bass subwoofer, and I need some help troubleshooting an issue with the power amplifier board. The board uses an IR2153 driver and originally had two SLW20N50C MOSFETs. Unfortunately, these MOSFETs burned out. I replaced them with two TK20J60W MOSFETs; however, these also failed almost immediately.

          Here are some details:
          • SLW20N50C (original):
            • Rated for 500 V
            • Typical RDS(ON): 0.21 Ω
            • Continuous Drain Current: 20 A at 25°C (13 A at 100°C)
            • Pulsed Drain Current: 80 A
            • Avalanche
          ...

          Unknown transformer : how to find a good replacement part ?
          by the_rem
          Hello guys,

          I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

          I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

          Grundig Vision 9 37 9880 T USB (Chassis SR) TV Repair Help - Distorted Subwoofer Sound and overall weird sound waveforms
          by LEECH666
          Good day ladies and gentleman!

          I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.

          This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).

          I think the PSU buzzing comes from one of the coils near the bridge rectifier but...
