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 […]

Guitar Amplifier Repair in Newark (Nottingham)
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 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 […]
This Bogner repair was sent over all the way from Liverpool on the recommendation of a Liverpool tech who makes fantastic boutique point to point gear, but doesn’t deal much in modern technology. The issue was with the DC heater supply which uses a switch mode power supply. Mr Bogner decided to use a switch […]
I’ve been hoping for a Hughes and Kettner Grandmeister repair since they first came out. Luckily for me when the amp’s owner saw my tubemeister repair blog he decided to send his amp all the way from Kent to be repaired at my Newark workshop. Apparently his local amp tech said ‘I don’t do modern […]
This keyboard amp repair was for a Worksop based violinist who uses the full range speaker with his electric violin. The amplifier was obtained second hand and had developed an intermittent problem in which the amp would drop out almost completely, leaving only a tinny high frequency signal. At first, I suspected that the LF […]
Just doing a quick write up of a powered mixer repair that’s going out today. It’s a Wharfedale repair, an SPX815 powered mixer that had no sound output from the left output channel. My first instinct when the Newark customer contacted me was to expect that the output stage had blown, but this turned out […]
It’s always interesting to get something in that’s a bit different – this was my first Acoustic Image repair. The amp is a Clarus 1, now discontinued. It’s a great bass amp in a very compact and lightweight form, made possible by the use of a Class D power stage. I’m a big fan of […]
This AV receiver repair, a Yamaha RX-V450, was completed on a fast turnaround for a local radio producer who needed it in time for a show. It’s got 6x85W channels and more inputs and outputs than you can shake a stick at. Although I’m well versed in solid state electronics, this is the first AV […]
I just came across my notes for an active speaker repair on a W-Audio PSR-8A monitor. It’s an affordable W-Audio PSR-8A that was being used in monitor duties by a Grantham based keyboard player. The job was competed last year, but I thought I’d blog about it now. The mains transformer had died. I replaced […]
This Fender Blues Junior Repair was an urgent repair job for a London based guitarist. I got the amp at 23:30 on the Saturday after a gig in Southwell near Newark and had it diagnosed by 11:15 the next morning before he returned to the ‘big smoke’. Actually, big smoke was obviously a problem that […]
