    Power Supply Transformer Markings

    Sir tedstruck . . . . Looking at the very first photo and at the left front foreground. The wire terminal has about 22 gauge wire wrapped around it to make connection to it . If you find the same gauge wire on the other three connections, there should be two like isolated windings that are...

    Power Supply Transformer Markings

    Sir tedstruk . . . . . More importantly, can you give the BRAND and MODEL number of the power supply itself. I got a blurred pic and no size referencing . . such as to an Amerikanski penny . . .but my bet is that the TALLER transformer is being your standby voltage . . . .power supply...

    Sencore TF46 Testing

    Sir Joebudd . . . . . Use that same transistor that you tested . . . .considering that it passed. Take its BASE to EMITTER junction and test it with both polarity possibilities that will be presented by your use of the RED and YELLOW test leads. Then do the same test again with BASE to...

    Looking for a specific transformer

    Sir Electric-T . . . . . If anyone is really interested i can post a picture of a my schematic (so far). You had better do that . . . . . . Because with your numbers being given below you are not giving us the current specification . . . . But just multiplying primary voltage times secondary...

    Looking for replacement Transformer

    Sir Pslade . . . . . Looking at the pristine coloration of your viewable magnet wire windings and the lack of any time related discoloration of the bobbin form . . . .I do fully believe that you just were being the recipient of one SOLID WHACK of line voltage or a lightning hit at your pole...

    Resistor?

    Sir Africangrey . . . . . . . (aka Mr parrot man ? ) Heh . . .Heh . . .Heh . . .. . . that low value sort of makes you wonder if they coiled the lead wires up inside as 4 or 4 ? coils and then poured in the ceramic slurry sealant into the cavity to cure. . As low of a value as that is being...

    electrolux/vernitron 12v dc re-igniter

    Sir bazz . . . . . I think that your problem possibly/ could have been related to the water, even though the unit is well waterproofed with an encapsulating covering. Looking as if possibly having used one TOUGH two part low viscosity encapsulant such as the Scotch #300 series. HOWEVER ...

    Identifying Component - SATA Drive Bay

    Sir davies2066 . . . . . Use a conventional soldering iron with a small tip and put a drop of rosin flux atop a / each pin and then take a perfectly tinned tip and do a quich touch . . . just long enough to see solder melt and reflow. Then move to a pin 180 degrees away and do its reflow. You...

    YAMAHA AST-C10 no audio

    Sir HellasTechn . . . . .aka Constantine . . . . Well here I am now, somewhat delayed by finding that all 3 of the available freebie schematics of that unit were all messed up in the bottom right quadrant, but I pieced together the best ones. Also, I see that the two major operative clues have...

    Yamaha psr e403 low sound output from speakers

    Sir samuel phillips . . . . . Dang . . .they had that simplified block diagram marked in error on the AUDIO output pins ALSO . . . . The correct ones are 5 and 3. At any rate since they are using two output stages that are normally working at a DC level of ½ of the supply voltage. With 5.65VDC...

    Hantek scope keeps ticking and wont turn on.

    Sir Mike_Lemon123 . . . . . Can you confirm, that your problem is usually related to the very FIRST time of an attempt to turn on the " cold " oscilloscope , or that you experienced this situation before it's now total competitiveness? Instead, you are only getting the old . . . ." Tic ...

    Whirlpool l1373 card (invensys 475560 )can't identify number for part circled inphoto can you help

    Sir brians2005 . . . . . Well . . . . . if you look and see if one of its lead ends is connected to the + of C022 and the other lead is connected to the + end of C023, you indeed have found L003. Furthermore, if it ohms out as being an open circuit; you are in need of another L003 which is...

    How do I replace this pot with 2 knob pots, coarse fine.

    BY JOVE . . . . I DO believe that you gots it ! . . .now. (Your drawing 34975 attempt, had the 20K pot installed in the wrong leg, of the 200K pot.) CAVEAT: With your 200K pot, its rotation to the right increases the voltage. On your newly added 20K pot, you have shown 1-2 joined vice 2-3 so...
