    X-Fi 7.1 "Home Theater Cable" (3x 3,5mm to 8x RCA): Where to buy? / Cable assignment?

    I gotta say, the odds of getting 6 incorrectly wired cables, is pretty small... but then again, my luck is just as bad. Keep us posted on what works and what doesn't!

    Tektronix 475A Display problem [Horizontal?]

    Got the Big capacitor today in the mail! so now I should be able to go after the bridge with no problem and replace both at the same time.... Just for giggles I attached a picture of this mammoth :-) now I've worked with 1F caps before in car audio... but I've never opened a piece of...

    Battery Help?

    Steve brings up an interesting question.... at least to me... How will you be re-charging these? assuming you will need to do so?

    usb fan question

    Just out of random curiosity, who's your ISP? I used to work with AT&T a lot, and their semens speedstream boxes and some of their westell boxes would get BLAZING hot according to the customers.... I generally told them to call the tier 1 DSL people and tell them that their modem was getting...

    Tektronix 475A Display problem [Horizontal?]

    Steve, yup,the last image is the one that IS on the regulated line (+15V) the middle image is the unregulated (or what I think to be) line. I misquoted which images were which, but the actual image title is correct. I was having a similar discussion with my friend and his father... they...

    Tektronix 475A Display problem [Horizontal?]

    More updates Okay, so I have replaced the C1448 capacitor (dipped tant.) with one of equal specifications, and the problem has not gone away. I have also found another unexplained test point... with a strange, half-assed saw-tooth.... which frankly I'm still trying to figure out where in the...

    envision h712a (maybe radio shack) no screen

    Just so you know, the Brand of the monitor/TV you have is actually made by AOC. Radioshack has sold them for a while. If this was about 10 years ago I would say go into radio shack and have them thumb through the RSU catalogs... but its not. As far as anything goes, your best bet is a service...

    X-Fi 7.1 "Home Theater Cable" (3x 3,5mm to 8x RCA): Where to buy? / Cable assignment?

    Well what I can suggest to you, and this may sound a bit strange, but if you find 2x 4 pole cables (like the kind for an older stereo output for a video camera) and 1x 3 pole cables, you would effectively have the same thing. For example: 2 of these (4 pole)...

    Wide Trace - Harris 3133 25mhz dual trace scope

    I'm certainly not claiming to be an expert by any means, but what you are describing is kind of similar to what I am seeing in my scope... I'm working on mine still, but here's a link. https://www.electronicspoint.com/tektronix-475a-display-problem-horizontal-t232993.html BTW, I don't know if...

    Tektronix 475A Display problem [Horizontal?]

    Update: Okay, So I have been pretty busy lately... and I have another project in the works at the moment that I am trying to see if its recoverable... but thats a story for another post. At any rate, so I have ordered the BIG cap and a few little doodads... (couplers) from a Tek part...

    Tektronix 475A Display problem [Horizontal?]

    Its the darker blue one to the left of the ceramic disc capacitor, in the 3rd of 5 shots (Titled C1448-Side.jpg). looks like dipped tantalum... not 100% though

    Tektronix 475A Display problem [Horizontal?]

    Okay, so I'm going to be getting ambitious soon, I am going to be heading down to my local high quality electronics store... and no, I'm not talking about The Shack. I'm not knocking them on their stuff... I worked there for 10 years, had a great time, I just don't think they have ANYWHERE near...

    Gateway Laptop Capacitor

    I will be agreeing with steve on this one, just based from what you are saying... the capacitors failing are fairly unlikely... it is possible, but I would be looking into other things first. The first thing I would check is to see if Windows (I am assuming you are using windows) gives you...

    Wierd keyboard problem

    A quick question, when you are playing this loud chord, are you doing this while its on batteries or an external power supply (wall wart?). I'm thinking if it is a wall wart, its possible the problem may lie in that as well... just a quick thought.

    VLF transmitter & antenna

    I would honestly agree with Dave on this one... There may also be a way to "piggy back" using a different frequency, like put a receiver on to the existing transmitter.... sorry if that doesn't make a lot of sense. What I envision, is basically attaching a higher frequency reciever to the...

    Intel Atom N550 Motherboard - COM EXPRESS form factor

    I would like to start off by saying I am no electronics engineer, but I can say that I do quite a bit with the small form factor motherboards mainly in netbooks/laptops/highly customized equipment. I can say that to build one from scratch, is no small feat. most of the time, you are looking at...
