    Having trouble identifying a diode needed for a repair.

    Agree . . . . . The two diodes of a line frequency Full wave rectifier circuit Researches out as 1N5804 400V 3A diode.. . . . family and the units solder connections shows some heat stress in the past. ALSO doesn't that TVS diode sitting beside them also seem to look cracked all across its very...

    Creative T3200 speakers help

    Sir Uros MIlosevic. . . . . . . I just consulted that units operational manual as its quick start set up, which gives little more than labelling of connections and is being shared in 8 languages. When I saw your last pictures, there was the separate 20 pin IC which I then researched out as...

    Basic Animated Christmas Light Controller

    Sir Maxwell. . . . . . . In your animated GIF I see no animated flow occurring between positions . . . . it's just a switching on- off of two positions . . . which then seems to create a quite satisfactory animated effect ! Seems like a solution would just be to replicate the RED...

    Reed switch

    . Netrack. . . . Would it now be logical . . . to consider your other aspect, in the the operation of the solenoid. Of course that would be the simplest Neanderthalic crypto like consideration of the utilization of 1 through 3 reed switches for the activation of the solenoid. That would be the...

    Vintage doorbell issues

    Sir neevo . . . . . . . The big question is still if the coil is open or if the RED contact area is oxidized and not contacting. Considering that the presence of the three metal film resistors in series were valid . . .which I never have seen used. . . . the markup NOW has the missing one...

    Help the Noob, identify missing parts on simple circuit.

    axel sandi. . . . . . . As requested . . . . here is the mark-up of where all of the "lite bubs" (lamps) go into the unit. Their one shared connection, is a commuon buss a l l l l l l l along the edge of the PCB. If you just have ONE lamp . . . . move it between positions to test out all...

    Reed switch

    Yep . . . .only one 12 VDC supply involved, and those are referenced as being the two positive and negative terminals of same. ( Those two lines above were created immediately after Sir Haralds comment and have been carried forward in page cache memory of the laptop that they were composed...

    PCB for Dishwasher repair

    Sir cjcharles . . . . . . . Did you give back info on the RED circled area . . . as I view it, it possibly just might be some ferrite beads on a wire. I CAN make out a 200 and 100 ohm surface mount resistor and a centered transistor. Notice that they make no effort to assign designations to...

    What can you tell me about paper capacitors?

    Sir {cog} . . . . . . . That which you show, I find to be a DAMN good capacitor, HOWEVER, if you find any of THESE. They are at the top of the list of the ROGUES GALLERY of bad capacitors . . . .they DEFINE the conditions of bad capacitors of their type. EXAMPLES: 73's de Edd

    Need help identifying a component!!!!

    Sir Tony Does this supplied info now answer all of your questions. With your units application shown a the very top as being one of a spike snubber pair across that driven inductor. With the old General Instrument 61A spec falling in "a hole in the ground" in the specs of the new parent . ...

    Where would I hook up 2 speakers to this amp?

    a continuance . . . . The initial info was clarified by your confirmation that the system was indeed using that power IC. Until you gave me the bottom of chassis foil pattern, it was not apparent that the manufacturer had deviated from that stock/data sheet schematic on the connections that...
