SOURCE: peavey classic 50/50 keeps blowing fuses.

Rob,

I have a classic 50/50 as well and re-tubed it with JJ el84s, vintage teslas and mullard 12at7s. As long as you replaced it with EL84s, I can't imagine that the output would be increased enough to damage the OT. When I got my 6505 Combo, one of the 6L6s was bad, and it kept blowing fuses and howling like a banshee. I would think that an OT problem would result in a significant loss of output...or none at all. I've gotten DOA tubes from a few places. I would suggest swapping each tube out 1 by 1, until you find it...if that is indeed the problem...before you pay the cash to have it worked on.

Hi chillin884

Not a good sign. Something has gone wrong with the output stages of your Peavey. It is not a good idea to continue plugging it in as damage may occur to your speakers. I suggest you take it to a decent music gear repair guy for a look see and give you a quote to repair These heads, like all Peavey gear, are pretty solid and worth repair. Sorry to be the bearer of bad news like this, good luck

regards
Graeme

A few things can cause it. Bad ground\bad power supply filter capacitor\bad low level op amp IC. You most likely have a bad power supply or trouble at your input jack. Good luck!

You might have a ground problem. Does it do it in different outlets or when you take it to someone else's house? One easy solution to ground problems can be running a three prong to two prong adapter on the power cable. Give that a try and see if it helps.

SOURCE: Static Noise from guitar amp.

I take it you have made sure that both the cable to the distortion box from the guitar and the cable to the amp are both good. From the description you give, it sounds like there is no signal getting to the pedal. If the cable is good, then the next likely suspect would be the input jack on the fuzz box. Try wiggling it a little with the guitar cable in place to see if it is loose. Some input jacks are unbelievably cheap and flimsy. A crackling sound (static like) is almost always a bad connection. If it was the output jack, I would think that the guitar signal would come through a least a little bit, but you might want to try wiggling that one, too, if the input jack isn't the culprit.

Another possibility to check is the battery, but this doesn't seem as likely. Some effects units devour batteries, especially units that use 9V batteries. I have a multi effect pedal that kills a 9V in about an hour.

Peavey classic chorus 1991 -how do you connect a distortion pedal the power amp jacks at rear tried affects loop in front bid drop in power-do you connect same way as effects loop with send /return


Pedals operate at a different level then rack units that go in the effects loop.
It needs to go in front of the amp input. Guitar to pedal to amp input.

Peavey speakers making no sound


Try connecting them to another amplifier...you can use the speaker output of a guitar amp as a quick test. If the amp (and mixer) check OK, it sounds like you are about to become good friends with your local speaker reconing shop.

Remember...Distorted Audio Can Kill Speakers even at low volumes. It happens because sine waves become square waves. Google it for additional information.

The voice coil on the cube speakers must be scraping against the magnet.Or the speaker cone must be damaged causing it to flutter at low frequency where there will be large cone movement. Try removing the phono jack from your musical instrument/ guitar and touch the tip of the jack with your finger. You will hear a hum, now turn down the volume and listen to the speakers very closely and see if you can identify the flutter. All the same you will have to fix the speaker or replace it. Have you ever dropped the speakers, if so the speaker frame could have warped causing the scraping noise.

You may have damaged the variable resistors (the volume controls), you can purchase replacements from a local Electronics store (if UK based try Tandy). Otherwise have you checked the speaker itself for damage? You may have split the speaker which will need to be replaced.

Useing a Peavey XR 800F Powered PA Mixer/Amp which develops distortion on output after around 60 minutes. Also had gear linked to all inputs at the time, three mics, 2 guitars and keyboard. Any ideas...


First of all confirm if the speaker impedance is not lower then the recommended Ohms at the back of the Mixer speaker socket.You can use an 8 Ohms speaker on a 4 Ohms amplifier but not vise versa .
Next see if the fan on the mixer works. If not the Amp is getting very hot and this will lead to unwanted distortion. You can confirm if its a heat related issue by playing the mixer at low volumes for more than an hour and see if it distorts.

Wires to main speaker are, Yellow & Blue witch one is the positive ?. Also I am getting distortion from the clean channel even at low volume, the speaker is Peavey 1230 model 8 ohms.


Yellow should be the positive. Try plugging in and reversing. The louder of the two is the one in phase and the correct wiring. If the speaker is pushing out when playing , it is in phase and correct also.
The distortion problem could be a speaker going out. It may not be totally blown, but may be verging.
Holding your hand out as wide as you can push against the speaker lightly. If there is a rubbing or scratching sound, the speaker could be damaged.If it moves freely, and there is no scratching its okay.
Another possibility is the clean channel may have a channel volume set to high. Make sure the clean channel volume is set lower than the master volume otherwise you can get distortion on that channel too.
Good Luck.

PLUG YOUR LEAD INTO AMP TURN UP JUST A LITTLE SEE IF IT BUZZES WHEN YOU TOUCH THE END OF YOUR CABLE.IF IT BUZZES THEN THE FAULT IS IN YOUR GUITAR MOST LIKELY THE ACTIVE WIRE HAS COME OFF THE INTERNAL GUITAR PLUG.

Hi, Peavey Classic Guitar amp , Has NO SOUND


Hi Mike,

If you switch on the amplifier, do you hear nothing at all?
Or do you hear low level noise or hum out of the speaker?
Don't know if you're technician.
If the tubes are glowing, you can measure the high voltage.
Check also fuse 3 and 4, thats the neg. voltage -27V and -14V.


regards,
Gerard

My amp won't play distortion.


Hello all you have to do is turn your master volume down to just barley on then turn your pre amp volume somwhere about 2:oclock depending on how much distortion you want ajust your volume on your guitar a little past halfway to give yourself some headroom in case you need to turn up some while you are playing! just think of it as your guitar is your first pre-amp then your amp is second preamp in line ,that is your over drive ,then the master volume is how loud you want the overall volume i hope this help's ya!

Peavey Bass Amp TKO115s


Start with a clean setting - zero cut and zero gain on the Eq. Play a song close to the amp, and then move away, playing the same notes. Do you still get the distortion? Change lower the input gain and repeat the test. Lower the output gain and repeat. Are any outboard distortion pedals in the mix, such as overdrive? Eliminate them. Run straight through from your axe to the amp. Check for any distortion settings. Set everything including reverb to zero. When the distortion disappears, this is your base setting.
Change only ONE parameter at a time. When the distortion comes back, you have found your problem.+
