I hear strange noises from my amplifier, what could cause this?
A number of things can cause unusual noises to be heard through your amplifier. Please refer to this list of problems and possible cures:
- Clicking/buzzing sounds. Try placing your cell phone in another room separate from your amplifier and see if the sound disappears. Other devices such as police radios can cause this. Wait a day to see if the sound returns.
- Static, popping, or ringing. This is most commonly a preamp tube. Try replacing the preamp tube physically closest to the input jack. This is the first stage preamp tube that is most susceptible to static and microphonics (ringing). If this does not cure the problem, try replacing each preamp tube one by one until the problem disappears. You may also try tapping on each preamp tube with your fingernail or end of a pencil to check for microphonics.
- Humming. Maybe your amp forgot the words, or this may be caused by a number of things:
A. Amplifier plugged into the same circuit as a device with a motor, such as a refrigerator or air conditioning unit. Try moving amplifier to another part of the house and see if the hum disappears.
B. Faulty power tube. If this is suspected, please have amplifier looked at by a qualified technician.
C. Faulty reverb wire. Make sure reverb wires are well secured to both the jacks on the chassis and on the reverb pan.
D. Fluorescent lights. Turn off all fluorescent or neon lights.
If none of the above solved the problem, please contact us through tech support email, or refer to a qualified technician.
