Guitar Amplifier Repair

We see many more guitar amplifiers than any other form of electronics stage equipment to repair, it's not because they are more problematic to failure it is just they are more popular and are often used for other things such as bass amps, piano amps and so on.

There are two main technologies we repair in guitar amps, this is solid state, and valve.  The term solid state simply refers to no moving parts and all 'solid' referring to the silicone transistors and FETS used to amplify and deliver the current needed to the speaker.  Valve amps however use electrons travelling through a vacuum to amplify the current.  The blue glow tinge you see on power tubes is plasma and is as close as you can come to seeing electrons moving.

Both amplifiers technologies contain dangerous voltages and users are not recommended to start prodding around inside.  We have had many amps in over the years where a video clip on 'repairing amps' is used and often creates many more faults.  For many people their guitar amp is their tool to earning money, and needs to be carefully repaired and looked after.

 

We're authorised Blackstar, Yamaha, Victory Amps repair agents, and recognised by all the leading brands as a repairer, brands include Marshall, Fender, Orange, VOX.

Orange Glow From Valves But No Sound. The Valve Is OK - Right? 

Unfortunately the orange glow is just the heater element. 

How often do I need to change my valves?

This is subject to personal taste really as long as they've not shorted or failed otherwise physically.

These parts often receive the most abuse and are the first to crack (pardon the pun)...
