I need a wiring schematic for a crate vfx5212

The distortion channel doesn't work, and there's all sorts of burn marks on the board, looking to fix it, but don't have a clue what things are supposed to be.

There is probably a setting that is wrong. The left channel is the default for mono operation. Look in your user manual regarding "PAN" which controls the output going side to side. You MAY be "panned" clear to the right. When you plug into the left, it is the default so in spite of being panned right, they would send signal to the left IF nothing is plugged into right.

I have a Crate CR212 it started to hum/buzz today. It would not play out any sounds other than the noise. I unplugged everything and still it hummed. I unplugged the unit, check the fuse and replugged and...


Are all the tubes lighting up? they should glow like dim light bulbs. If not, replace them with the same model type (12ax7, or EL34 for example).

Often there are two fuses, one to protect the speaker and another to protect everything, it sounds like the latter fuse may be burned out. take it out and take it to radio Shack for exact replacement.

Need schematic for Crate PCM-8 DP+


Without a schematic you can still trace the circuit to locate the fault.

Put a music source or sound source into the bad channel and a good channel, and with an oscilloscope or with a pair of high impedance headphones with test leads on the ends- you can set up a low z headphone with an impedance match trasformer, make sure you have test prod ends on one of the leads. The other can go to a chassis ground. Start at the input and work your way forward comparing the signal between the good channel and the faulty channel. When you lose the signal or you encounter severe distortion, you are in the vicinity of the defective part.

Common failures are a Deffective 4558 or TL072/TL071/TL074 IC chip. You may have a faulty electrolytic capacitor, or even a faulty bypass caoacitor in general. Bad solder connections, even a broken fim resistor.

With the IC chips, the usual power pins for an 8 pin plastic or ceamic DIP are pins 4 and 8. usual outputs for the 8 pin are 1 and 7 the remaining pins are the inverting and noninverting inputs. 2 and 3 and 5 and 6.

Also check switches and especially those with interupts on the input and output jacks- they can get dirty.

I have and old Peavey Mark IV bass head. I want to know if it is possible to remove the crazy 8 or 10 pin footswitch input and replace it w/ a 1/4 in plug. There is only two wires running to this craz


2 wires plus ground needs a stereo 1/4 plug. Don't know Mark 4, but Mark 3 has 2 button fs with 3 wires plus ground. Schematic here: http://el34world.com/charts/Schematics/files/peavey/peavey_mark_3_bass_with_pa.pdf
shows 3 wires plus ground. Stereo plug does not have enough connections, only ground plus 2 wires.
Count the pins of socket and find DIN plug with proper pin-out for socket. Search google for DIN plugs.

Crate csx24 sound board- the mute lights will not light. Sound works but lights will not light.


USUALLY the Mute LED's for the switches ar operated by separate contacts on the mute switch an a resistor current limit for the LED. I could NOT find the schematic for this board, HOWEVER some Soundcraft brand mixers do NOT have illuminated Mute switches... Not sure about your particular unit.

While moving, the equalizer slides / controls broke off . Where can you find them and are they replaceable? Crate Telluride Accoustic amp.


Yes, the pots are replaceable. Removing them from the circuit board requires solder removal tools. DO NOT atttempt to remove these with solder wick. The new high temp solder (ROHS) will surely cause the board to be damaged. I use an Ungar powered solder removal system. The parts can be found at DigiKey.com or Mouser.com. The part value is marked as is the taper which will likely be an "A" or "B" suffix. Search for potentiometer, slide. You have to exactly match the circuit board pin layout. The distributors have links to the manufacturer's spec sheets to compare. First thing is to measure the travel, then find ones with the right mounting, then the resistance and finally the taper suffix. The parts are typically between $1.50 and $3 each.

The effects do not work on my Crate VTX 350 H, what's wrong with it?


Are you getting sufficient power to the amp?

Could be a loose connection inside the amp (such as a wire), a bad component, or a severed ground. Many possibilities here. If you know electronics, take a multimeter and start testing all the components. Look for any burn marks, check for broken solder connections, and continuity test all wires. Be careful since amps can hold a deadly voltage for a good while. Be sure to drain the capacitors before doing anything else inside it. If you do not feel comfortable doing this, you can take it to a electronics repair person. Keep in mind that Crate is one of the harder amps to fix because most of their components are surface mount.

Casio CT-670 Tone Bank keyboard completely dead


How familiar are you with schematics? I've just found my CT-670, There where marker marks on the keys. I cleaned it up. I took it apart as one channels had no sound. I love this machine. I want to find a manual for it also schematics would be very helpful for me too.
I would suggest looking inside for burns on semiconductors. or loose soldering. I need to replace a chip that has no cross reference... that I've found yet... I think it's an amplifier but need to spend more time on it....
