Guitar Amplifier Repair in Newark (Nottingham)
COVID-19 UPDATE: I’m currently still taking on work. Please see this page for more information.
Keld Ampworks is a guitar amplifier repair service repairing audio electronic equipment in Newark (near Nottingham). I provide a fast and friendly service that is competitively priced. Please have a look around, I’ve repaired amplifiers by all of the main manufacturers (Fender, Marshall, Vox, Peavey, Laney, Mesa Boogie) and kept my customers’ boutique and unusual designs (Cornford, Carvin, Dr Z) in top condition.
Most of the amps that I fix are valve amplifier repairs, but I do see plenty of solid state amplifiers too. I’m happy to work on modern amplifiers like Line 6 and Hughes and Kettner, but equally comfortable restoring vintage amps. Besides guitar amps, I also repair bass amps, PA equipment, DJ, speakers, HiFi.
I’m pleased to say that I’ve had many happy customers – if you’d like to check out some reviews of my service, please visit the feedback page (pun intended!). If your beloved guitar amplifier or bass amplifier is in need of repair, servicing, upgrading or modifying, then please do get in touch to discuss your needs.
My History in Guitar Amp Repair
Keld Ampworks Guitar amp repair was established in 2010 and moved to Newark (Nottingham) in 2012. Before Keld I studied with the Maughan Amplifier Company, a well-respected guitar amplifier repair and manufacturer in the North of England. I gained extensive experience of amp servicing in this position and during my time doing repairs and sales for Gear4Music. Although guitar amps are relatively simple, when repairing gear it’s important to have a thorough understanding of the theoretical as well as the practical and for this reason I completed a Masters in Electronic Engineering from the University of York.
As well as the repair and design of guitar and bass amplifiers, I currently work as a development engineer designing amplifiers for a world-leading audio engineering company. As an active musician, playing in a range of different bands, I really do understand how crucial it is to have your gear in top condition!
I don’t get many ENGL amp repair, so I was a bit annoyed with myself for not photographing this one. I’m grateful to the owner for helping me out by sending me a photo.Here were the symptoms, in the words of the customer: Overly noisy (hissing / popping) on both clean and overdrive channels at […]
This LabGruppen repair was actually for me! As is often the case with people in this trade, I never quite get round to repairing my own gear because I’m so busy with customer’s work. This LAB1200C power amp died with a spark and blown fuse at a New Year’s Eve gig with Newark soul and […]
This is a JHS pedal repair for a good friend and guitarist who now works in London. It’s a two pedal overdrive. Its a Sweet Tea V2 – sounds great! The pedal had been damaged by the use of the wrong power supply. It was a fairly simple repair to complete. No schematics are available […]
This Blackstar HT100 repair was completed for the co owner of an exciting new Grantham based venture ‘Melody Music Rooms’ in Grantham. Melody music rooms are a rehearsal space, recording facility and teaching space located on Westgate in Grantham . It’s the brainchild of a group of Lincolnshire and Nottinghamshire music teachers who wanted to […]
This is the world’s most popular valve amp , meaning I get a Hot Rod Deluxe Repair quite regularly. The amp has two common faults, which are well documented. The first, and most common is the grey ‘IC’ (Illinois capacitor) electrolytic caps which are prone to failure. Fender use these presumably because they’re the […]
This Peavey Classic 30 repair was a bit of a nightmare! It arrived with a fairly basic problem – the amp wouldn’t turn on. This was down to a loose screw. It held the mains fuse holder internally. When this came loose, the fuse holder was dangling in mid air and shorted mains directly to […]
This Polytone Minibrute Repair came in from a Lincoln customer with an obnoxious hum problem. This unit is probably form the 1980s The issue was solved by adjusting the output stage bias point and improving the connection between the screw mount power supply capacitors and the power amp stage. The amp is a bit of […]
Another first for Keld Ampworks – the first AMI Jukebox repair. I’ve turned down jukebox repairs in the past because I naively had visions of a 7 foot unit arriving in my rather small workshop! This customer was quick to clarify that the amp unit itself is quite small and transportable from his Lincoln location. […]
Actually, let’s start with a slightly different question… Are valve amps louder than solid state amps? They often are. Take for instance a Marshall MG30 and a Vox AC30 and crank them to the max clean volume. There’s no question at all that the Vox will sound significantly louder. Or take a Fender Blues Junior […]
