Not a fuse. First thing, to check your speaker (amp unplugged, of course), touch the + and - speaker connections to a 9V battery. If you don't hear a pop sound then your speaker is blown. Thus, no output sound. If speaker is OK, then the output IC is your problem.

I have a crate vtx 212 amp and the power comes on but none of the chanels comes on and no sound what so ever comes out. Nothing looks burnt or corroded idk what the problem is i need help lol


If sure that power is reaching and getting into unit, then confirm that a signal is also reaching unit. If both are positive, then your gear is FUBAR if signal is going into correct input.

Crate flexwave 120 head effects malfunctioning


That is probably a momentary switch that is dirty and sticking. These onboard effects on guitar amps are usually nothing more than a computer sound card and I've found bad connections going to and from them as well. I do think that switch is dirty and sticking, though.

Well i used to have this really bad guitar that has this grounding problem (humming all the time unless u lower the tone or touch the strings or any metal object on it) well i always blamed the guitar for...


Hi,

This would only mean two things:
1. you have a bad capacitor in the circuit or the grounding on the circuit is broken and not filtering the obvious line noise from the circuit.

2. You have what is called, dirty power. That is when you have some kind of electrical device plugged that generates line noise which can be even a florescent light as they generate line noise.

Please take the following steps to narrow down the issue.

Take your setup and plug it in some where you know others can setup their rigs and it is using clean power. If, the humming goes away then it is dirty power where you originally setup.

If, it is still humming then you will need to take your equipment to a qualified marshall dealer have them look at it.

Google: Randall Padilla, that's me.


What could be an issue is if the cabinet is a 4 ohm cabinet and you plug it into the 8 ohm output. of the RT100 ... IT WILL BE LOUDER that way... for a LITTLE while... till the power tubes get gassy from overheating and the sound will GO AWAY. VERIFY the impedance of the cabinet and plug into the correct jack on the RT100. Every RT100 will do this... it is GROSS abuse of the amp if you plug 4 ohm speakers into the 8 ohm jack. Some of the power tubes may conduct so heavily when they get gassy that they will cause a hum before total failure. The tubes will first get red, then orange plates and that drives metal ions out of the plates, then they get a purple glow and eventually blow the fuse or something in the power supply.

Crate TX50 DB has noisy DSP circuit when rotating the DSP pot!


When you are changing the DSP effect on the fly, static or noise is NORMAL !!! The DSP is changing the data and having to recalculate on the fly and doesn't mute itself while doing so which results in "garbage sounds out".

The bypass setting should NOT get any tone UNLESS you have feedback going on. If your guitar can "hear" the speakers in the amp, the strings can vibrate and get feedback going.

Unplug the guitar and see if high freq tone is still there on bypass. If the tone is in the musical range, then there is a problem if nothing is plugged in. If it is a VERY weak, very high frequency tone, this may be the digitizing noise from the DSP. On bypass, the audio is likely to still go through the DSP, just not be modified by it.

I have a small crate rx15 solid state amp. The power light comes on, but no sound comes out of either the amp or headphone jack. No buzz etc....


Power light means very little. If unit has a preamp output, plug a set of headphones into it and see if you can hear anythin going through. (it will be weak). If you can, the power amp section is bad. Take in for service.

Dirty high switch on a Crate practice amp


NEVER use switch cleaner such as DeOxit on pots !!!!!

I have used CRC226 available at Home Depot electrical dept.

I SUSPECT that the resistance element in that pot is cracked. This is common if the knob sustained a hit. Replacing the pot is the only cure if the element is cracked.

Reviewing the schematic, ALL audio passes through the wiper on the HIGH tone pots. If the wiper is intermittent, so will be the sound.

If your unit is solid state amp, the pot looks like a 10K ohm LINEAR taper.
If you have a tube type, then the pot is a 250K ohm LINEAR.

Note that the other tone pots in the units are AUDIO tapers, but the high is a linear taper.

Get repair parts from either DigiKey.com or Mouser.com

No sound coming out of speakers when turned on


If you get absolutely no sound, not even a pop when changing the standby switch, this probably means the rectifier OR the switch has failed. The red light just means power is getting to the power transformer... probably fuse is OK.

Crate bv120.no power or sound..no lights..f6 fuse has 160 ohms...


did you change out the fuse? could be a tranny going south. if you change the fuse and you still get no power, then you have a fried power transformer. they are relatively easy to replace. look on ebay . get the numbers off of the existing one and start web searching. something will come up. if not email me on my contacts tab in my website yostamplifier.com we can troubleshoot. you should see the custom blue voodoo i built and gave to my little brother.
