Sadly I’m sharing the story of a line 6 DT25 repair nightmare. The amp was blowing fuses. This was a relatively easy diagnosis despite a not very repair friendly construction. The power transformer was damaged, by a short, probably on the primary side. After a bit of research it appears that the line 6 DT25 […]
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 thought I ought to document this Yamaha THR repair whilst I could still find the photos! The amp had fallen from a height and the DC power input socket was damaged. Simple enough job, or it should be! Yamaha supply a an external converter to convert the mains supply into useable DC, but they […]
Orange VT1000 valve tester repair. I recently had to repair my own Orange VT1000 valve tester. I thought I’d post the pictures here. You can see the bad joint that was causing problems with the Octal Valves. If you need an Orange VT1000 valve tester repair, please get in touch.
Today I repaired an EBS amp repair on a 2 hour turnaround! The customer brought the unit to my Newark workshop from Nottingham. EBS are a swedish brand. It’s the first time I’d worked on an EBS unit, though I’ve played alongside bassists who’ve used EBS gear and been quite impressed. I contacted their technical […]
This Blackstar Series One repair from February was a bit of a mess! The amp had unfortunately received the unhelpful care of another repairer who had left the amp in a terrible state. If you don’t like to see damaged PCBs, look away now. It was brought to me because it was blowing fuses at […]
This is the first Blackstar ID30 TVP repair that I’ve come across, but there wasn’t much to the job. The owner had lent his amp to a friend and the tip of the jack socket had fallen off inside the amp. I was really impressed with the build quality on this amp and it was very […]
This Fender Brownface repair was something of a labour of love here at Keld Ampworks. It’s a fascinating amp – having started life presumably in America, it’s got a 110V transformer. At some point it made its way to Belgium, where it was ‘converted’ to EU voltages, using a rather scary transformer bolted to the […]
This Fender Blues Jnr repair was another urgent job completed quickly for a customer who needed it for a gig in Lincoln on the evening it was dropped off. He brought it to me reporting that something ‘wasn’t right’ with the sound. Upon listening to the amp I could tell what he meant – under […]
I’ll admit this Blackstar HT5 repair had me confused for a bit. It was brought to me from Stamford Endowed School, which isn’t that far away from my workshop in Newark, it is just down the A1. The amp arrived with no sound output from the speakers. The valves tested fine, one 12ax7 and one […]
I love getting something new on the bench, so this Henriksen amp repair got me quite excited. It’s a Henriksen Bud combo. I hadn’t heard of Henriksen before, but after a bit of research discovered that they are a US based high end solid state amp, in the same market as the Polytone and AER […]
