The easiest way is to get a multimeter that can measure transistor gain (hFE). The cheapest one I have found is from Hosfelt: 9202 - Multimeter, just $12.95.

By far the most comprehensive and comprehensible book on transistor bias and gain that I've run into is "Practical Transistor Circuit Design and Analysis" by Gerald Williams; 1973 McGraw Hill, TK7871.9.W53, ISBN 0-07-070398-1. See similar questions...

The first transistor radio was produced by a company called Regency Electronics (originally called I.D.E.A. Corporation). The company had been approached by Texas Instruments to use TI transistors to build the first commercially-produced transistor radio. This occurred only after the big players in the field (such as RCA, Emerson, and Philco) declined to take on the project. Regency was a maker of television antenna boosters at the time.

Transistor radios have been produced all over the world. Produced first by countries with the largest electronic technical pool (the United States, Japan, and several European countries), radios moved on to be items that could be easily manufactured anywhere. Radio manufacturing locations shifted as competition forced prices down, and labor became the major expense. After the U.S. See similar questions...

In the early 1960s, transistor prices had come down enough that certain manufacturers began to increase the count of the transistors in their radios, ostensibly to offer better performance. However, in most AM-only radios, only eight transistors actually are active in the circuit. The extra transistors were merely soldered into the board and didn't do anything! (In fact, some manufacturers used "dud" transistors. See similar questions...

Early pedometers were mechanical and used a moving lever arm to count steps. Electronic pedometers now detect movement through a spring loaded, counter-balanced mechanism that records vertical acceleration at the hip. Pedometers measure the number of steps a person takes throughout the day. See similar questions...

There is no real way to get more gain out of a single Boostaroo Amplifier. We do sell a higher gain amplifier model that is twice as powerful as the Original Boostaroo. It's called, The Boostaroo Revolution Optionally, you can also daisy chain one or two Boostaroo Amplifiers together. This will provide you with a significant volume increase.

Weight change is usually minimal (body fat composition increases in the breast and hips sometimes - adding curves). Appetite may be increased during the first few months of pill use. To prevent weight gain, decrease fats and increase fruits and vegetables in your diet and exercise regularly. ^ Contraceptive FAQ | ^ Top See similar questions...

This refers to the sensitivity of the gyro. When the gyro senses an unwanted movement it commands the tail servo to move in the opposite direction to compensate. How much it tells the servo to move is the 'gain'. Ideally the amount of gain should match how much the helicopter was rotated so that it stays pointed in the same direction and does not move. If the gain is too high then the helicopter over compensates. The effect you will see is the tail will bounce back and forth. See similar questions...

This means the gain can be adjusted in the radio. A non-remote gain capable gyro has a control on it that you use a screw driver to turn for more or less gain. A remote gain capable gyro has an extra plug that goes to the gear channel. With this type you can use the gyro menu in the radio to adjust the gain. If it's an older or cheaper radio that does not have a gyro menu, then you can use the gear ATV to adjust the gain. See similar questions...

I need to find that JRC4558 chip that's in the TS-808, I heard you can get them from old radios and other voodoo sources! Yes, you probably can. Or, you can buy the current chip that sounds the same as the original - so close you can't tell the difference... from MOUSER. The part number is:513-NJM4558D. There's more about the TS and chips here. See similar questions...

For the most part, go to www.nteinc.com,click on Semiconductor (for searching) and type in the transistor number. If there is a replacement made by NTE, it will be shown and you can look at the data sheet if it's online. On the bottom of the page will be a picture of the pinout. IN MOST CASES, the pinout will be exactly the same as the original part. If it's different, the NTE web site will note that the pinout is different. See similar questions...

Try this: go to www.nteinc.com,click on Semiconductor (for searching) and type in the transistor number. If there is a replacement made by NTE, it will be shown and you can look at the data sheet if it's online. Since NTE and ECG share the same numbers, you should be able to find either NTE or ECG parts at your local electronics store. Usually these replacements will work fine. Only in very special circumstances will the replacement parts fail to work. See similar questions...
