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!

Fender Repair – Blues Deville

Fender repair time! This is a lovely Blues Deville fender amp that’s seen some serious loving! The owner has been gigging it for 15 years. Unfortunately, first the Low gain input died, then the high gain became intermittent. The owner asked for a full valve amp service and I promised to repair the jacks as […]

Laney Repair – RBX700

This Laney Repair was an RBX700 with an annoying intermittent problem that I was at first unable to replicate. The customer descibed the fault as a volume drop-out after about 10m or so of playing. On the bench at the repair shop it worked for several hours on several occasions without any issues. When I […]

MXR Repair

MXR Repair – Carbon Copy

This poorly delay pedal repair had the same problem as this MXR repair job from last year. This is a known ESD fault with Carbon copy delay pedals ‘of a certain age’. As you can see on the photo, this Delay pedal uses surface mount technology (SMT). This can be a little fiddly to repair, […]

Cornford Repair

Cornford Repair – MK50 ii

This Cornford repair came in for a service. Conford amps are often beautifully constructed amplifiers that sounds as good as they look! The owner uses the MK50 ii bias switch to use 6L6 and EL34 valves. He was using E34Ls (different to EL34s!!) and wished to have the valve amp biased to move the EL34s […]

Vox Repair – AC30CC2

Much as its nice to be taxed by a complicated repair, I love a simple job too! Despite a number of problems, this Vox repair was an easy fix for the customer, in fact, thanks to a dodgy screw the hardest part was getting into it! The customer complained of a crackle and intermittent volume […]

Hughes & Kettner Repair

Hughes & Kettner Repair – Tube 50

This Hughes & Kettner repair is a tube 50 brought in for a valve amp bias. The Tube 50 is a fixed bias amp, meaning you need to bring the amp to a tech to have it adjusted (confusingly!!) by a technician. The opposite of fixed valve bias is cathode valve bias. Confusingly cathode bias […]

PA Repair

PA Repair – Prosound 1000

This PA repair, a Pro Sound1000, was brought to me with a couple of reasonably common symptoms. One channel was producing no output, the other channel was very quiet. To be honest I’m surprised that the internal fuses hadn’t blown. The symptoms pointed towards what is probably the most common problem with solid state PA […]

Laney Repair

Laney Repair – GH100L

What is it with laney amps that makes me forget to photo them? This Laney amp bias GH100L just needed its bias adjusting to accommodate a new set of EL34s. The GH100L is a fixed bias amp, which means the bias is adjusted (and quiescent current is fixed) by a technician. The opposite of fixed […]
