    Seeking advice to connect wires to power source other than twisting wires together

    wire to wire they sell a clip/clamp that is placed in two places on the splice and is up to code. They are sized by wire guage so buy the right size. You have to use the clips or its not code...

    Transformer wrapping

    In replacing a melted transformer, even when I know the wire gauges, it seems kind of fundemental to count wraps! I have bundled wire on sticks up to 50 wraps on an air core with no change in voltage! So I am also assuming the primary as an exciter, and the draw on the secondary also will play...

    Transformer wrapping

    Here you go! Assuming there.are no ideal circuits, and the saturation point of a coil is instant, common sense dictates that all equipment be metered. I have yet to see a built in transformer with a meter on it!

    Transformer wrapping

    I have read alot of articles on transformer wrapping, and I am really worried about attempting to make one for a specific purpose. That is to say that most of them talk about the linear value of the wire and that if you need more signal use more wraps, if you want more power use bigger wire(or...

    Large chip with no markings

    This was in a pm144mt II practical periferals old phone modem.. It sits over where chip 99 is supposed to go.. What is it? A multi M resistor? A chunk of magnetite to induce current? Should I put it back on the board? [Mod edited - resize huge image]

    Frankenstein's Components.

    I saw one open once. It's just a mem reader. It uses two mains to handle the res. Prob. Really simple pnp configuration. At a glance that is!

    Mainboard with reworks need comparison to same type

    Forboding electronics device death... ouch. Well I am bull headed stubborn and quite able so its gonna be a while... I tried to reset and setup the system, I had an old disk that I copied the system setup files to.... didn't work yet. Called THESONIQ who said he is the only authorized repair...

    Laser fence notes....

    Does anyone in know the distance that a small modular laser can be separated from a modular eye before it fails?

    Small motor with 104 cap bridge between terminals.

    Thanks...I needed that!!! I think the circuit driver might be carrying so much power that the induction motor is saturated too fast for recovery. Assuming that induction carrys the same power as the driver circuit, maybe, The coils that push the armature exciter is charging but reaches...

    Small motor with 104 cap bridge between terminals.

    The replacement of the 104 cap worked... But I am sad to say my reliance on the ceramic disk numbering systems has decreased... where a 104 is 100nf a 103 is 10pf So with the 87nf cap on the motor, the highest speed would turn fine, but reducing the speed with the pot, caused the motor to stop...

    SD-1 Ensoniq Battery low message test

    Will try that. hope the best practices are still working afterwards. The PS is looking ok on my synth after a few meterings. May be bad board contacts where the battery connects, or the OS has reached its limit...(I already ordered the next upgrade one and am patiently waiting for snail mail.

    how do i fix this pls

    Hope it works. :vintage not head theory.... the color that they have left out of theory, is green. Green is usually used for ground. I'm not color blind but will be after this thread.

    Frankenstein's Components.

    Title "The Gorcapgoverner" One of my childhood freinds told me that if someone could invent a device that could detect power, access that power and use it, that they would have a device that could be useful for everything that was electric. Imagine a reading lamp that you take into your living...

    Interface connector help

    High power, low power, signal line, line voltage, communications, strap or jack, the connector should fit the application. There really isn't a flush mount pin-out, but I have seen a corner pin-out that looks flush when the connector is in it. Personally I like RCA jacks, they can be inset so...

    Wanted to let you guys keep up with my drill down on the greatest music synth biggest problem sortee. I am following the repair manual and the PS is where it all starts. I am not(by a long shot I might pass the drinking fountain on the way in)a professional electronics ingenor or a novice by...
