What you'll need for this session:
Screwdriver for height adjustment
Does your guitar make tones that you really didn't ask for? Dual "out of tune" tones? Mushy tones? Weak outputs? Hmmm... sounds like your pickups need to be at the right height. Not to worry, in most cases, we can fix that.
First off a quick "how duz it work" explanation. Most Electric guitar pickups are nothing more than a magnet with very thin lacquer coated copper wire wrapped thousands of times around it. The two ends of the coil go to a potentiometer with lets more or less voltage pass through. The magnet which has a field of electrons "floating around it in a field, they get "excited" when the steel string is plucked, going back and forth, and the electrons move through the coil of wire at a certain speed (frequency!). After they go past the potentiometer, and to the amplifier, the frequency of the electrons, the voltage, creates the sound. Your high school science teacher helped you to become a rock and roller! Depending on the location of the string to the pickup, is your sound.
Weak output or mushy sound. Most of the time this means the pickup is just plain too low. Using your screwdriver, tighten the screws located next to outside edge of your pickup. If you have two screws on one side, adjust each one accordingly so that the pickup is parallel to the strings. Rule of thumb is about ¼ " from the strings.
Dual "out of tune" tones. Jimi Hendrix used this quite a bit. This was the sound on his strat with stock single coil pickups because the pickup was too high and created a false harmonic so to speak. Almost like having the string pressed down at the pickup. Again it has to do with the physics of how a pickup works. The magnetic field creates this false note. Instead it adds the extra tone... usually not in tune with the plucked note. Don't get me wrong, Jimi did great no bones about it. However, that may not be the sound you are looking for. So, lower the pickup or pickups on your instrument until it doesn't have that sound. One note to strat players, in order to get the right pickup height, you may need to adjust the neck angle using a thin shim under the end of the neck in the cavity. If you aren't well versed in how this is done, talk to your repairman. We do talk about this in our classes that we teach.
Anyway, this should help on the tone of your guitar.

Cellular Amplifier technologies
These Days everyone has cell phones with many needing a booster for the signal strength. But how do use Cellular Amplifier Technologies to improve your signal and make sure you have the best response for the important calls you make. <br>
There are various ways to improve your cell phone signal. Cellular Amplifier Technologies are one of bestest ways to rectify your week signals. With the advantages of Cellular Amplifier technologies, every phone is getting better and therefore the signal response also is getting better. With more cell towers being built daily, newly released cell phones should be getting more bars than older phones. <br/>
Many cell phone providers offer subscribers to upgrade their phones which are strongly suggested to support the new features there are several ways you can use Cellular Amplifier Technologies depending on whether you want a portable or permanent solution. There are basically three kinds: in-car, home/small office, and RV/trucker. Since we are modding the RV, let's stick with the purpose-built solution. <br/>
The Cellular Amplifier Technologies can be had in a nice kit from Wilson Electronics that will be sure to serve your most demanding needs. Options in the kit include a booster amplifier, antenna, cabling, cell phone/Air Card adapter, and mounting hardware. <br>
If you are in an isolated part of your area, the antenna might increase you one or more bars since it is more powerful that your cell phone antenna which usually is small or internal to your phone. At the same time as Cellular Amplifier Technologies is the most costly method of giving a much needed power boost to your phone, a power booster is an excellent investment, and they work in a very straightforward fashion. <br/>
This hooks the cell phone via a wire to the booster and the booster then is hooked to the antenna, and given the portable life of this solution you can easily use Amplifier Technologies in areas with limited service with no difficulty. More modern models of phones have internal antennas which have all the benefits of an external antenna with one major planned benefit: an internal antenna is much stronger and fit due to the fact that it is not showing to the elements as much as its external counterparts. <br>
When traveling in a vehicle, one of the best ways to increase your cell phone signal is to use a 3 watt cell phone signal booster on the outside of your car and uses a wire to connect directly to your phone. The antenna is actually moveable meaning that it does not only need to be build up to a car but can be used in another place. <br/>
Any electronic gadget is as useful and as durable as its weakest element, and the major problem with the external antenna is that once it is broken, the entire unit is out of commission. This poses concerns not only in terms of the hassle of getting the cell phone repaired, but the inconvenience and expense as well. <br>

schematic for a Radio Shack PA amplifier model MPA-125?
does anyone know where I can get a schematic for a Radio Shack PA amplifier model MPA-125 (catalog number 32-2003)?
I've tried Radio Shack, ManualsParadise.com, ServiceManuals.net, and fileshare/eshop/bg and of course I've Googled for it and still no schematic. I'm trying to repair this and a schematic would sure be a big help.
I tried http://www.agtannenbaum.com/ (thanks for the link) and I have had two different Radio Shack dealers contact the main company for a schematic and they just don't have it. Any one else have a suggestion?
RADIO SHACK HAS A WEB SITE. RADIOSHACK.COM. YOU SHOULD BE ABLE TO CALL A STORE AND HAVE THEM CALL THEIR SALES MANAGER OR DISTRICT MANAGER TO FIND ONE FOR YOU. THATS WHAT THEY ARE THERE FOR, OURS WAS A NICE GUY.
