    nostalgic american made...Bose

    This nostalgic American made...Bose which from Goodwill has no display.

    After this http://www.fixya.com/support/t518635..._style_model_5
    I really don't know which caps to change, so I use ESR meter found this 2 caps. (Pic 7)

    One question, no display how come you know is display problem, Is the power turn on or not ? By use this UK made meter ( if I am right?) in Pic 4. I put in current mode (this meter has 4 digits current display better than anyone else.) to diagnostic where the power is on or off.

    http://www.ebay.com/itm/Power-Meter-...-/261262542723 for reference only.

    By the way,Goodwill is a charity shop, thrift store (U.S. and Canada), which are the similar shops in UK. ???

      VFD displays need "high" voltage, check the display power supply stage.

          Yes in the uk we do have shops like this also called charity shops although most my local ones dont sell electronics the only one in my nearest area that sell electronics is british heart foundation stores but too be honest the prices are really high and unless the item has been pat tested they dont sell it.

              Thanks for your reply. vinceroger69: british heart foundation stores but too be honest the prices are really high and unless the item has been pat tested they dont sell it.

              Same as Salvation Army the prices are really high had changed to Goodwill, which is the wonderful place to find good old cheap American made electronics.

              Hola. cpt.charlie: look the last Pic I already fixed by change 2 badcaps. Gracias.

                  Is it possible to test small ceramic disc capacitor with analogue meter?
                  by chth96
                  I read EBOOK of Testing Electronic Component and found that

                  "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
                  Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
                  It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

                  Is it really possible to test small ceramic disc capacitor with analogue...

                  Modification of a Fluke multi meter that uses three AA batteries to use a 14500 lithium ion battery
                  by sam_sam_sam
                  I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board

                  I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery...

                  Changing the scale of an analog meter
                  by jorpec
                  Hi

                  I want to change the scale of an analog meter, to monitor the charge of an li-ion single cell, so the needle at the end would point 4.2 volts and the 0 on the meter would point 2.5 volts or so, i tried to add diodes or a zener in series with the meter but the changes of the ambient temperature also changes the voltage value on the meter
                  I wonder how i can accomplish this so the meter would be precise at any temperature ?

                  Thnaks

                  How an incandescent light and a ESR meter ** friend**have a machine blowing fuses
                  by sam_sam_sam
                  About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well

                  Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for

                  Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer...

                  EDMI ATLAS MK10 Electronic Meter Discussion
                  by Stephan Mathers
                  Greetings, new guy here but always interested in the crazy universe of modding

                  We just finished construction of around 25 vacation houses, all inside the same private area.
                  Each house has 3phase power , and we bought an atlas MK10 meter for each house (25 meters total ! )

                  The metering on a per-house basis is done privately. Its not done by a utility company. The utility company will only charge us for the total consumption of all 25 houses together.

                  Id like to do a small modification on the firmware of our MK10 to make it easier identify each house's...
