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 […]

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.

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!
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. The fault was with the power supply and is a known design flaw […]
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 […]
The first task for last week was an Ashdown 550 Touring Repair, brought in from a Newark customer bec because the amp wasn’t making any sound – actually it was making a very weak tinny sound. I like ‘no output’ or low output repairs – they’re often easy to fix. Fortunately this was the case […]
This recent bass preamp repair was for a friend, bass player for professional party band the soul thieves. The preamp came from one of his backup instruments. Identifying the circuit was a bit of puzzle due to conflicting information on the web. The bass preamp has bass and treble controls, a blend for the pickups, […]
This wireless mic repair came in from the singer of Newark soul band the Acetones. Both units powered up but no sound came from the receiver when the mic was used. Upon investigation I discovered that the transmitter and receiver were able to communicate. They use 2.4GHz. The unit has 6 wireless channels, all of […]
In October last year I fixed this wah pedal repair for a lincoln customer. The pedal would not turn on, possibly as a result of the user plugging the wrong power supply in. Often pedals aren’t economical to repair, but a unit like this is normally worth it. In this case it was a fairly […]
My customer brought this Laney VC30 from Worksop to my Newark workshop complaining that the clean channel distorted. It’s a pity, because he’d kept it in pristine condition! Two other attempts had been made at repairing this fault. One by Laney themselves, and one by a local electronic engineer. Both had fixed the problem temporarily […]
A smoke machine repair, brought to my Newark workshop by a Grantham based DJ. This is a fairly simple unit: A power supply, a thermostat and a relay to control the power to the smoke heater. There is also an external remote on a 6.5mm 3 pole jack cable. The customer was finding that the […]
