Repairing Costs of Other Common Guitar Amp Issues

Guitar amps require high voltage to work. If they’re exposed to high potential from time to time it can end up causing some fatal injuries. That’s why basic maintenance of amps is required on a regular basis. 

On a friendly note, amp repairs can be done at home by yourself if the problems you’re facing with your amp are minor. 

Let’s discuss a few amp repair problems other than the ones mentioned above and what they can cost you. 

1. Amp Tube Replacement ($50-100)

The two main tubes: preamp tubes and power tubes, are those that you can replace after their time limit in order to boost up your performance. 

Preamp tubes provide voltage, and power tubes provide volume, which is the main purpose of amplifiers. While replacing amp tubes, it’s necessary to turn off the amp first and let the tubes cool first before touching them. 

Simple amp tube replacement can cost you 50$-100$, according to the model. You can have your amp tubes installed, and your amp rebiased in this budget.

This price would probably go up if you got more wires or tubes to be replaced in your amp. Check this link out to see the best-selling amp tubes online. 

2. Guitar Amp Fuses (Variable Charges)

Sometimes minor faults can completely disrupt your guitar amp. A blown littelfuse, for instance, won’t let the current pass through. 

However, you won’t need professional help, and you can replace them yourself too. You’ll just need to replace the installed tube rectifier with one of the same models. 

Although it might not be sufficient to rupture a soldered point, this could move the wires within the jack and cause a spark. Changing it with a new guitar fuse will cost you about 1$ to 9$.

If the fuse happened due to a faulty rectifier then you’ll need to change the rectifier tube as well which can cost anywhere between $15-60 depending upon the quality and model of the tube. 

Note: You can keep spare tube rectifiers and amp fuses at hand to stay safe in such situations!

3. Professional Help For Guitar Amp Repairs

Although you can do amp repairs at home by yourself, there are some repairs that demand professionals. 

Let’s discuss a few problems so that if you find yourself facing them, you can go seek professional help:  

• If the components present on the circuit board need to be replaced.
• Power transformers need to be adjusted or replaced.
• Replacement of filter capacitors.
• Adjustment and cleaning of potentiometers.

There are various online shops that offer amp repair services and mention variable charges for each repair.
