After fixing my turntable, I think I need a new cart (maybe I just "need" one ). This one is a shure 3x of unknown age (bought the TT at a garage sale for $10) and the vocals sound terrible on it... I don't need a DJ or scratching cart, just listening. I also don't have much in the way of...

I am trying to find out if my turntable needle/cartridge needs replacing (likely) or if it's just the wiring. Looking at a cartridge from the back (wiring side) what are the 4 leads (L, R, G)? 1 2 3 4 Also, any suggestions on how to align or calibrate the pressure of the needle?

I recently got the Billy Joel "River of Dreams" CD (copyright 1993 so not really that old...) and immediately after taking it out of the case I noticed that it was considerably heavier and thicker than other CDs that I have handled. Also it has another shiny ring (similar to the one around the...

To prepare for the Millet MAX build, I needed to get something to test transistors with. Also, my HP bench DMM doesn't measure AC V or current, so that's a plus too ). I decided to get the HF DMM suggested in the BOM. Grrr...I placed my order on the 1st, and recieved confirmation on the 6th...

Just in case you didn't know, this article gives a good description of how to replace it: http://www.command-tab.com/2007/03/1...d-hard-drives/ and gives the model number for an 80GB 4th gen iPod Hard Drive: MK8007GAH It also gives a model number for a 100 GB 5th gen HD: MK1011GAH...

This is my first project, so just to see if I could do it, I bought all my parts from Radio Shack (possibly part of the problem ). The only opamp they have is the TLO82. The test source is a 4th gen Ipod photo from the headphone out (so I have volume control). I have put everything together...

Perhaps this is a stupid question, but I was wondering. Say our circuit does not require an exact resistance, but we want to have relatively matched resistors. Since our goal goal is to match two resistors (for example withing .1% of each other) and the measurements occur in a very short...
