    What Part is This?

    Sir Johnathan . . . . . An Optical " collusion " ? Do a double check. . . . . Take note of the gauge of the bare tinned wire size to the right bottom. Check at the right top corner and see if you don't see the same tinned wire coming out and making a sharp bend to the left and then...

    What exactly is making this beep noise?

    Sir Greg . . . NOPE . . .that's not it. That YELLOW 330 is being a fixed inductor You are looking for a piezo-electric beeper in possible case variants as are being shown below your s.w.i.i.i.i.i.sh picture. The hole in the case and the internal acoustical chamber is as important a the...

    Filter Capacitor - Identify pins

    Sir DeejayPnS . . . . . Hmmmmmmmmmmmmmm . . . . . you must be involved with an old tube based radio or audio amplifier and trying to take care of eliminating some serious HUUUUUUUUmmmmmmmmmmmm . . . . . coming from its speaker. You mean that the only pin is the "positive" and the metal...

    Need Help Identify a Capacitor and a Resistor

    Some one here . . . . Disc ceramic capacitor 12 picofarads at +/- 20 % tolerance rating . . . . . . probability of that unit of being good is. . . . >> > > > > 99 86/100ths percent. Resistor . . . . . that you seem to be dissing, just because it has 1 lead broken . Probably is also good...

    Filter Capacitor - Identify pins

    Sir DeejayPnS . . . . . Looks to be reading as a 50 ufd / 450V screw can mount electrolytic capacitor. It is to be screw mounted to a hole in a metal chassis. As you tighten the large mounting nut it grounds the metal aluminum casing to the chassis, and makes your negative connection.. That...

    12v dc output power supply

    Sir Austarlie . . . . . I'm holding off on visual posting of a board and parts layout pending some on hands research made by you, for some confirmations. The boards comp and foil sides views are just being temp hosted . . . . . until all parts are identified. Looks like you have yourself a...

    Whirlpool control board Ivensys L1373

    Sir juan 2017 . . . . . Referencing my #3 post circuitry just above . Go to Q801 tach amp transistor and monitor at its TP 56 test point. See if it is responding with a voltage variance at different rotational speeds. Use low range AC or DC monioring . . . according to whichever gives you the...

    Comedy Thread

    Yep. . . . .that requires a VERY-VERY exacting and precise 9-----99-----999---> and their decimal variances of lb / kilogram set of weights . . . . . . or it just WON'T work out for you.

    12v dc output power supply

    Sir Austarlie . . . . . With no tech info on the unit . . . . obviously its being a low thru mid power linear regulator circuit . . . . if using a 3055 and the 313/330 being its driver. If the resistor was a 10 ohm it could do a good burn . . . . if being a 100 ohm it could discolor and...

    Low volume

    Sir SP1LLCO . . . . . Does that hold true for ALL functions . . . like - - - - - AM radio----FM radio----CD player ---- Cassette player ? Also, plug in a set of headphones and see if that is being the same way. 73's de Edd

    Dual Speed Control Circuit

    SIr mortier . . . . YES . . . . . do you want to make another like unit, or is this one being inoperative ? If an inoperative unit and considering the pull of that motor and no hidden fuses blown, the most likely part to fail is the BTA12 triac. If replicating the unit, I see all parts being...

    Equivalent Capacitor for 220r16 c4 (2)

    Sir haishivakeshav . . . . . Considering that the two units are being in a shown 293D casing . . . . Check these dimensions below . . . As you can see. there is the basic case height and then the NUMBER of electrolytic layers that are required to build up your capacitance in the internal...

    Need to drain off curent.

    Sir Jongig . . . . . A continuance . . . You said . . . The reason I think the motors are the key is because if the motors are shorted the elevator going down barely moves so if the electricity is regulated the motors would maintain a certain speed. My point of interest is the aspect of if...
