    Need help identifying part

    Sir Warhawk . . . . . . . Ohhhh Tayyyy . . . I have us all started up now, but will need some feed back on parts and readings. I have seen your HOT running metal "filumum" resistor on three different Pee Cee Bee pictures, as what looks to be either a 470 ohms or Sir Marduks 560 0hm . . . ...

    Help with figuring out a blown thermistor (?) in a 12v power supply unit (S-360-12)

    Sir Discoveryellow. . . . . . . Good job ! Looks like the evaluative testing that you performed , gave the unit a shakedown and confirms that the whole unit was apparently not damaged at all. That 60 w lamp limits the power out, only by using 100 or 150 watt lamps would you get more PS...

    Old car radio circuit

    Sir Richard902 . . . . . . . With "old car radio" actually falling in the 87'ish vintage Just in case you couldn't relate the units physicals to the schematic. Here is a blow up with the two RED and BLACK wires being the BATTERY DC Power input The outside choke involved will probably be...

    Solid State Pinball Chime ---Capacitor???

    . Sir ramrod213 . . . . . . . If they are in stock, looks like their offerings in a 50VDC rating are 1000 and 2200 ufd or a summation of those multiples. Lucky you have access to a store there . . . . here I sit in a 6.4 million megopolis . . . with Radio Shacks Interplanatary Headquarters...

    Solid State Pinball Chime ---Capacitor???

    Sir ramrod213 . . . . . . . You have it shown right . . . .now its just a matter of progressively raising the capacitance to adequately meet your reserve demands. 220 or 470 or 1000 or 2200 or 3300- ufd ? and use a 50/63 VDC rated cap or higher. That would all be related to the repetition of...

    Solid State Pinball Chime ---Capacitor???

    Sir ramrod213 . . . . . . . If the Rectifier and storage cap are there already, it only seems logical that a progressively larger capacitance will extend the permissible drain down time. Since one doesn't typically make scores at very fast rates . . .right ? 73's de Edd

    Help with figuring out a blown thermistor (?) in a 12v power supply unit (S-360-12)

    . Sir Discoveryellow . . . . . . . On the unit, see the YELLOW incoming line with your AC line input until it gets to the arrow tip with your AC to DC rectifier and then that is the point where those thermistors come into play. That DC is to be sent to the left to those two large black...

    Can this wire be soldered?

    . Sir Williev. . . . . . . See if you need any more info than this previous posting provides: https://www.electronicspoint.com/threads/soldering-connections-for-my-replacement-3-5-stereo-plug.279014/#post-1694176 In the interim . . . .It certainly looks like ELVIS has left the arena ...

    Digital Converter Boxes... 2016

    Sir philpense. . . . . . . Since you are being Amerikanski . . . .and thereby receiving NTSC. I think that the only improvement that you would find, would be for upgrading to one of the Radio Shack units. After seeing most all of the other units . . . if not all . . . . the ONE outstanding...

    I need a Wiring Schematic for a 2/12/75 amp charger switch

    . Sir Duane Jones . . . . . . . You gave us no model, but is this it ? That specified part is color marked up on both schema and parts list. Quite a special little slide switch there, with its 3 positions and do note the cross jumper used on the middle terminals, should you opt to use...

    wanted : 12vdc to 24vac 5 watt schematic

    Sir mark krawczuk . . . . . . . so i DONT need to rectify it to dc. the ac goes straight to the pcb. OK then, I will need to further clarify my initial thought train for you . The "24VAC" aspect immediately triggers the fact that a GOOD amount of commercial security cameras...

    wanted : 12vdc to 24vac 5 watt schematic

    Sir mark krawczuk . . . . . . . Is that "24vac" spec chiseled in stone,as you are probably then going to have to rectify it to DC anyhow, aren't you ? If so, would a PRECISE frequency output be a requirement ? 73's de Edd

    Low power inverter circuit

    Sir pidja . . . . . . . Check this referencing and see if the pin 2 and pin 7 improper assignment, as is being designated in RED LETTERING, might be relevant to your situation. But it looks like your schematic is also in agreement . . . . .there must have been an earlier schematic which had...

    problem: CLSENSE shutoff of an LM3524 based circuit under all circumstances

    . Sir Mark Sulkes . . . . . . . I'm looking at your engineering drawing sheet and its time era on its dating. Look back to the 1980's and see what might have been your specs on that older unit that might differ. Tejas Instrumentations is now their big Sugar Daddy, and claim...

    LG Flatron L1942T-PF monitor no power

    Sir mikey5791. . . . . . . My suspicion of your IC, is because when you are testing those connections you are ohmming through two series arranged Collector to Emitter transistors junctions inside of the IC, which should not read that resistance. Just try that test , using a single...
