    Sir mike1856 . . . . Indeed . . . you have found the Speaker cut out relay . . .our item of interest. This unit may not be exactly like yours but you can see the marked on connections of interest. This unit needs 24VDC to be at the GREEN pair of terminals in order to close connections...

    Food mixer power supply dead.

    Sir Lake_M . . . . . We can work with both side pics of the power supply . . . . as you provided. Seems like the CON1 and its wiring between the boards is having . . . . A common DC ground as the central WHITE wire and A DC voltage supply carried to the other board via the YELLOW wire...

    MCS 3847 Integrated Amp Noisy Left Channel

    Sir Kilgore Cemetary . . . The noise has become more of a start and stop sputter, so getting any readings while it's acting is In my test situation above, the amp and left speaker only have to be listened to for the typical time that the noise has been recurring. In which case you would...

    Need Help/Advice How To Power Setup

    That size of socket and its LED lamp equates to a cars tail light / stop light incandescent lamp, and that LED equivalent will be eating up somewhat less power. You will just have to do an observed timeout to see how long that battery powers it, until dropping just below 10 volts battery...

    Problem - Tuner amp AKAI AA 1175

    Sir mike1856 . . . . . Looks like both Sir Dorkes and my manuals are different from yours.( With that high of a fuse count that would be about one fuse per each 4 kilos of amplifier weight.) The two 5 amps should be for both of the AF output to speaker feeds. BUT I don't see them on my...

    Food mixer power supply dead.

    Sir Lake_M . . . . . The inductor was blown, and the Schotky diode was blown. From the boards construction / design I would take the use of a " Scottish " ( well . .Hell . .that's what Spel-chek, sez it shud be ? ) diode as being the D8 diode at the very top of the board, and being within the...

    Need Help/Advice How To Power Setup

    Sir goodalejason . . . . . ( Whut's a Throwingchicken . . .Version V3H ? ) Any how . . .confirm if that is being one single heavy BLACK wire coming from the lamp socket . . .which I would consider as normally being properly wire coded by use of a RED wire. Now, of those two GREEN ended...

    MCS 3847 Integrated Amp Noisy Left Channel

    Sir KilgoreCemetery . . . . . I'll be providing this info soon with a new reply. Getting the noise to start and stop on cue is currently impossible. Back when you had the noise presence on the left channel and used the 47 ufd cap from the input of the PA and effectively AC shunted all of...

    What is this SMD component?

    Oye . . .OYE . . . . . When the party of the first part . . .thrice removed . . . returns . . . . .lets just have him place a small neo-biddy-ninny-ninny -yum-yum magnet up against said "D" part, and just see how much of a resistor that it is. (Considering that there is being some slight...

    MCS 3847 Integrated Amp Noisy Left Channel

    Sir KilgoreCemetery . . . . . You come up with 1XX series numbered parts as C126 and C125 caps, but we have only been shown the C2XX series of caps being on the PA board via the photos. If it is like other circuitry the C125 will be related to the Left channel, and part C126 for the Right. I...

    What is this SMD component?

    Sir alert . . . . Careful there now . . .CAREFUL . . .as you are now answering your own question. The way that I am "reading the board" is that RED OVAL circled SM semi is not following the most common lead assignment protocol, so lets basically see that the center pin is going to the...

    Help with a Yamaha RX-V640

    Sir Jeanguypataterubberboot . . . . The next step would have been to place a DVM in DC Volts AUTO / OR / 50VDC range and have its neg probe to ground. Then you power up and and probe each of the "dot" marked points and log down that voltage found on each resistor. 73's de Edd

    Please help to buy those components

    Can you copy relevant pages from the book, so that we can evaluate its content here ? Or the name of the book and its author, as we might also find it . 73's de Edd

    MCS 3847 Integrated Amp Noisy Left Channel

    BEFORE you have to pull the board for bottom photo access . . .BUUUUUGGGGER ! . . . .confirm if the elect cap and its AC signal grounding of YELLOW A terminal doesn't silence the left channel noise .

    Sir KilgoreCemetery . . . . . . . On photo post #9 . . . .I can see that in your zest to get back to work on this unit, that you had left your enbalming gloves on ...aaaand it's back. . . . . . . is that being same-same as . . .its baaaaaaaaaack AND . . . you are such a pleasure to work...

    Help identifying a component please.

    The casing reminds me of the first generation of Fairchild LED's. Any chance that the intact LED will let you confirm the color of light emitted, as well as the overall brightness level and the beam spread pattern that it is developing ? Then just the sub in of another LED to compare...

    Sir Jeanguypataterubberboot 1. Your Avatar is giving me one HELL of an EVIL eye ! 2. With Jeanguypataterubberboot as your identity, it seems for sure, that you must have one HELL of a password that goes with that. Would the unit then stay on and play at that slightly reduced AC power input...

    Problem - Tuner amp AKAI AA 1175

    Sir mike1856 . . . . . The lights are on as usual but no sound coming from the speakers. That means that the MAIN 2.5 A AC line fuse at the top rear just under the dust cover is good. Wondering if there is a fused output to the speakers? NONE SEEN Have tried it with a CD and the tuner so...
