A lot of static coming from the amplifier when I switch on the gain. Is that normal?

Yup, I think it is normal. Do you have a manual for the instructions? You go see if there's something there about well, the static from your guitar. And I think its coming from the guitar. Good luck :)

if lots of wires, esp power cords, near spkr wire then may have hall pickup, or maybe bad neutral/ground somewhere\nunplug just the amp and see if still happens\nmaybe you just now noticed it - that is easily possible. you heard it once when your head was close and now you notice it always

If you use it alot, you might try cleaning the player. You can get a cleaner at most electronics stores.

Good answer to the reinstall on the NAV for the error message.\n\nAs far as the static and if the previous answers did not work, try thinking somewhat less geek. Common Sense often works. \n\nOften times, inexpensive speakers or headphones have very bad insulation to the wiring that plugs into your computer. Interference happens thus so does the static and hums.  Try plugging in different speakers/headphones and see if you get different results.

Not a real problem if you don't dig too deep. Quiet often, back in the days when I repaired speakers, the connection from the voice coil to the speaker contact wires would break from vibration. Un-winding just enough of the wire (coil) to re-do the connection saved many an expensive speaker.

Yes, its not uncommon, somehow it picks up radio signals...it just is picking up some frequency nearby...sometimes I get it through my studio while I'm recording...it generally goes away after awhile...try moving your amp to a different spot in the room. or to another room...it should stop.

Disconnect/turn down the sub woofer, \nor use a smaller speaker\nor connect the output to a stereo and use the equalizer to turn it right

You don't need much current at the input of an op amp, and 100 ohms with, say, 10 V (typical power supply V) across it dissipates a whole watt, so you don't want that low an R in a feedback loop or an input divider (power waste and heat being undesirable).  Also if you are using R-C circuits, a lower R means a larger C for given frequency response.  Too high an R though (in the megs) and you run the risk of picking up hum due to electrostatic coupling, and also loss of accurate gain due to leakage current.  So you'll see maybe 10K - 100K as a desirable range.

i'm more familiar with old ampegs, peaveys, and fenders. however it seems to me from what i've seen and heard of the 6100 that what you are saying sounds corect. a lot depends on what type of music you are playing, and what pickups you are running through it, of course. the crunch channel should give you more of a classic rock blues sound, and the lead should be more of a metal screaming tone, and i would think the lead would have a lot more gain than the other 2 channels. and certainly i would agree that there shouldn't be an excessive amount of 60 cycle noise. one thing i would try to do if you haven't is to set it at the 100 watt setting, i'm sure you had the preamp volume and gain set where you wanted it, as well as had the master turned up a bit. with this amp you should be able to get very clean tones, clapton sounds, as well as guns and roses sounds, but with a little MORE gain. it's hard to describe what it should sound like, you just kind of know. i've been playing for 34 years. my advice would be to either give it a little time and play around with the settings until you get it where you want it, and sounds right to you, or return it if you got it from a store and are not happy with it, or trade it for something you will be happy with. good luck.

Check to see if your raido is plugged into the same receptacle as, say, a computer, or TV - the noise is most likely a 60Hz humm caused by a common ground with these types of equipment.  Also, shielded cable between the radio and the speaker would be helpful.

An emitter follower has a voltage gain of very nearly 1 and a high current gain. It is connected with supply voltage Vcc at the collector and the load resistance between the emitter and ground. The voltage at the base will be nearly exactly reproduced at the emitter but there is a base-to-emitter voltage drop Vbe which is about 0.6 volt for silicon transistors. Vbe is nearly constant as long as the transistor is not driven too close to cutoff or saturation. The input impedance is high because of the transistor's current gain (called beta). For AC (e.g., audio) amplification, you typically bias the base at Vcc/2 which allows a signal swing of nearly + or - Vcc/2.

What's to know?\n\nIt's the typical offset voltage, or DC component of the output.  The signal is AC.

try an oscilliscope.  compare the input to output.\n\nif you have the right scope it will provide distortion values...\n\nyou will certainly see the signal degradation.\n\nof course th efirst question is - why would you run VGA for 100'?  Try an IP KVM - avocent.com works...

well it depends on what you were doing when it quit...if u were playing it loud and long it got to hot and burned up before thermal protection....if u were hooking it up you may have blown a fuse or again burned it up...before i junk an amp i open it up and look for any solder lines that may have got to hot and broke...if thats the case just reconect them....i used to do this to power acoustic amps..possible voltage spike on the rca line blew the input...i have gone through many amps....but it could even be the tiniest peice on the board causing it to not work....

check the input jack on the guitar....sometimes the the eternal metal will get  bent and not make contact with your cable plug......but definitly check your wires in the guitar......peace

I'll picture it for you...years ago when all the radios were AM Amplitude Modulation...when you drove under high voltage power-lines..you would hear static...with FM Frequency Modulation this will not happen..Higher Frequency.\n\nI hope this helped

(m)\n\nIn large computers, neutral to ground voltages are originated because nonlinear currents flow through the neutral wire. In general always when there is some current flowing in neutral wire, there will be a ground ot neutral wire voltage difference on output end, because there is no current flowing on ground wire. In some computer systems the voltage differences are considered to be problem, because it has been reported to cause cause improper behaviour like "hangouts" on some computer systems. \n\nIt is true that in some special cases neutral to ground voltages can cause this kidn of problems, but in those cases it is not to blame the separate wires, because the problem lies in some other place. In properly built electrical wirign network, the neutral to ground voltage differences will never be more than few volts and any properly designed electrical equipment should not be disturbed of this kind of small voltage differences. \n\nIf the equipment gets disturbed of this small main frequency voltage, claim the manufacturer/designer of that particular equipment for doing bad job. Computer equipments can be easily deigned to cope few volts of voltage differences between neutral and ground. Most of the modern euquipments are designed to cope this. \n\nIf the voltage difference between your neutral and ground is much larger than few volts or there is very good propability that there is somethign wrong on you main wiring. So it is best that an electrician goes and checks your wiring before more problem and damages happen. \n\nIn some cases the neutral actual to ground voltage is not the problem, but the wavefor of the voltage. Non-linear loads like computer power supplies and light dimmers can cause some considerable noise between neutral and ground. Such noise can be more problematic than just a simple voltage difference, but equipment should still be able to cope quite fair amount of it (EMC regulations etc.). If you have considerable amounts of noise on neutral wire used by nonlinear loads, then you can again blaim the improper design of the electrical wiring. This kind of problems can be solved by good wiring design practices: separate electrical wiring from main panel/transformer to the equipments which cause noisen and to equipments which are sensitive to it. This is good practice and keep problems away. \n\nIf you would have on those cases had a wiring with common neutral and ground wire, you would have terrible ground potential diffeences between different outlets. In cases were ther problems neutral to ground voltage differences in separate ground and neutral wire wiring start cause problem, a wiring with common ground+neutral wire there would be so much ground potential differences between outlets that any equipments connected to different electrical outlets and interconnected would work very erratically, you would propably cause many equipment damages. Computer sustems are generally much more sensitive to the ground potential differences than ground to neutral differences. \n\nThe bottom line is that separate ground and neutral wire is a good thing for many problems. It solves more problems that what it potentially causes. And in wery rare situations where separate ground and neutral wires cause some problems, in those same situations a wiring with connon neutral+ground wire would have caused much more but different kind of problems in form of ground potential differences. When taking account situation where computers are interconnected/networked, a good stable ground potential for aal equipment is much more important than very small neutral to ground potential. Separate ground and neutral wires is a good method to keep the outlet grounds at same potential, which is very important in networked computer systems.
