    maybe the original seller had the heatsink & fan as an option.

      Re: Old analog Power Supply needs your advice

      I have read your proposal which is much appreciated. I actually have most of the parts you mentioned but I need to find the time and energy to clean out my components drawers. in reality I am leaning more towards a digital adjustable power supply. but I will try the current one as it is just to see what it gives of course I will add a transformer for testing

        The power supply that have current control are the best option for testing devices with
        I have several of them and are well worth the money

        But if you are looking for something that might work for you try something like this

        https://www.ebay.com/itm/23443838895...3ABFBM-PDb1dZg

        https://i.ebayimg.com/images/g/MWcAA...fU/s-l1600.jpg

        One note the adjustment pots can be replace with multiple turn panel mount pots for easy voltage and current adjustments

        You could also try this one note this version does not have current control but is setup for transformer output nothing needs to be add to function

        https://www.ebay.com/itm/123257636761

        Here is another option this one also does not have current control but you can also convert one of the LM317 to current mode

        https://www.ebay.com/itm/11219716687...3ABFBMmJPb1tZg

        I hope this helps you with what you want to do

          Hi Sam and thanks for the support. yes how this has happened : probably a very bad soldering pencil without knowing it because I absolutely could not unsolder them blue Trimmer Potentiometer and I became obsessed to push them down with the soldering tip then it was a hell to free the holes yes that's what happened 2years ago

            yes it is good and cheap with 20amp but it measures from 06v or does it go to lower v measurement ? what do you think of this :XYS3580 WIFI Adjustable Buck Boost Converter DC 6V-36V 5A Power Supply Module but it only goes to 5amp

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
              by sam_sam_sam
              I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

              One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

              Modification to a ZD-987 desoldering/soldering station using a external switching power supply
              by sam_sam_sam
              I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

              I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

              Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
              by JimBanville
              The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
              Opened it up and discovered the power supply is making a faint clicking or ticking sound.
              I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
              I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...

              Russound CA4 Power Supply Repair
              by CMCM
              Hello Everybody,

              Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)

              Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).

              The outputs marked 12v and 20v are all measuring only 1v.

              The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.

              The capacitors physically look clean (no bludgesor leaks) and...
