The power amp blew... There is a marginal insulation in a circuit board that wipes out the rear-most power amplifier. Usually accompanied by sparks and smoke.

If the lights still come on for the effects window, then the power supply is OK and you are VERY lucky... have the unit serviced immediately.

If no lights come on now, the the power supply is toast as well. There will be about 20 components fried.

I know as I have repaired 4 of these... no fun, believe me!

My roland cube street starts making this really weird loud noise


Hi, Quick Check. Very often the input socket which is soldered directly to the circuit board, will have a broken solder joint. This is common on a very large amount of equipment. Try waggling the plug about and seeing if the noise comes and goes.
Easy fix, re-solder joint. Permanent fix, connect socket to board with flying leads, or fix socket to board with hot glue or epoxy resin.
All the best, Chris the Fader.

I`ve just bought a new Fender Telecaster Deluxe. When I plug it into my amp there`s a slight hissing hum. When I touch the strings it stops. I`ve tried it through a different amp & changed leads so


you may have a ground loop problem and when you touch the strings you complete the ground loop so the noise dissapears. make sure the amp is plugged into a proper grounded outlet. also there is an aftermarket ground plate that goes under the pick guard. that is what I put on mine to cut the emf way down. if you bought the guitar from a dealer take it back to the store and ask them why you are getting so much noise.

Likely the filter capacitors have a problem. Best to take this in for repair... it is ODD that there is noise with the standby switch is in standby... That makes no sense... In standby it appears that power is removed from the power amp high voltage so nothing should come through the speaker... Unles maybe one off the power tubes had a total meltdown which should have blown the fuse.

The power amp section has blown parts. You will likely find they use a chip like the TDA7293 as the power amp output and it will be blown, shorted causing the fuse to blow. These cost $6 from Digikey.com. Find a competent tech to replace it and use heat sink compound. Verify the part before ordering one. They come with leads bent either way so make sure you get the one with a matching suffix letter. When firing up after repair, put a 60 watt light bulb in series with the hot power lead to act as a current limiter... saves blowing fuses if there is another problem.

The guitar is not amplifying


faulty lead? when the lead is plugged in turn the amp distortion on (may be called 'gain') and when you tap the end that goes into the guitar with your finger you should hear a buzz. try another lead if not, and if it still doesn't work make sure that volume is up on the amp and the guitar. there may also be a knob in the back of the amp, turn that up too (but not all the way or when you do get it working you'll blow the speakers out).

My new SWR workingpro 12 has a low frequency permanent noise, any idee ? Maybe from the Power supply... Thanks, bolliger_rudolf@bluewin.ch


All amps make a small amount of noise (system hiss) but the amps own power supply should not cause a problem on it's own.
However if the frequency is around 50hz (the G 2 1/2 octaves below middle C on a piano) it is most likely due mains electricity interference or an earth (grounding) issue.
Here are a few things to try to identify the source.
  1. Could be a lack of earth (grounding) This is potentially VERY DANGEROUS and could result in electric shock if you touch a metal part of the amp or touch some other metal object (like a microphone stand at the same time as your guitar strings). Check the earth wire is firmly attached at both ends of the power supply lead.
  2. Could be a defective mains socket - try plugging it in to a different one, preferably on a totally separate circuit.
  3. Could be an earth loop. These can occur if you are using the amp with an output to a public address system or mixer that is also earthed because of a 'potential difference' between the two earths. Solution - use the balanced (xlr) output which incorporates an earth lift rather than the unbalanced jack output.
  4. Unplug any effects pedals, foot-switch etcetera to see if that eliminates the problem. Turn off any internal effects, including bass intensifier.
  5. Make sure any signal cables (guitar leads) have good quality screening and that the screen is well soldered to the jack plugs at both ends.
  6. Ensure signal leads do not lay along side (parallel) close to mains electricity cables but are well separated and only cross at right angles.
  7. Move the amp away form other electrical equipment that may have a powerful magnetic field (especially CD or DVD players, hearing loop amplifiers, radio microphone transmitters / receivers, mobile phones
  8. Turn around or stand in a different position - it might simply be the pick-ups in your guitar causing interference in the magnetic field of the power supply.
  9. Does plugging in or unplugging a signal lead / guitar make any difference? This particular amp requires only mono jack plugs a stereo (trs) plug may be shorting across terminals
  10. Does it change when you touch the strings with your hand? If yes check internal wiring and screening within the guitar.

Hopefully you powered your monitors from the SAME receeptacle as this device.

If one powers monitors at one end of a room from one receptacle and their mixer from the other end, due to noise spikes on the power lines, one can have one or the other damaged.

ALWAYS power connected equipment from the same receptacle source.

Your unit uses a 250ma fuse according to the schematics. Replace it with an identical type fuse. You have to open the unit and you will find it on the board in fuse clips. It is a glass type, easily seen and replaced.

NOTE: If it blows right away, take unit for repair.

This unit is very poorly grounded, much like consumer electronics so one needs to be careful what you connect to it.

Basically, I turned it on, played it, turned if off, went back to play it and I got a humming noise then it went dead!!??


I suspect either the power supply rectifier developed a short which would likely blow a fuse till repaired OR the power amplifier chio went bad. Most of the smaller amps use some version of the TDA2050 audio amp chip. It looks like a power tab transistor (TO220 stylle case) with 7 leads.

If it went, it did so for a reason... time for unit to be serviced.

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.

How to set up with amp and distortion pedal


With everything switched off. I will surmise that you are using the onboard battery with the foot pedal and not a power supply.
1. Plug lead from guitar/instrument into INPUT side of pedal
2. Plug lead from OUTPUT side of pedal into amplifier INPUT.
3. Turn amplifier volume to about 10 o'clock - to stop blowing your ears out.
4. Turn volume up on guitar to acceptable level.
5. press foot switch on pedal and adjust pedal controls to suit your type of distortion.
6. Play like Hendrix.
Good Luck
ps Just as an after thought rechargeable 9volt batteries are the way to go. I've been using them for years as I always get caught up in the power cable.
If you're going to add another pedal like a Phaser, Compressor, Flanger or what just use small connect leads between each pedal but always, always put the compressor pedal last in the line.
