Sadly I forgot to photograph the amp so here’s the stock Peavey repair image! I’m not the most djenty/hardcore kind of musician, but it’s hard not to admire the level of filth before feedback that the Peavey engineers have got out of this fiery monster. This amp is a 6505, which I believe is a […]
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!
Oh dear! This line 6 repair was a bit of a mess – you can see on the right hand side of the pic that the board has been burnt by some over heating rectifier diodes. Most pedals run from a DC supply, but a lot of line 6 gear uses and AC supply. A […]
I don’t normally ‘do’ hifi – the construction often makes hifi repair inconvenient, and I don’t get to the opportunity to rock out when the repair is finished. However I took this hifi repair on for an associate who was very helpful to the Engineering team I work with in my ‘day job’. It’s a […]
This 2205 repair came to me following an unsuccessful operation by another tech. The 2205 were a new step for Marshall – and were one of a group of amplifiers that formed the ancestors of many channel switching amps we now take for granted – including amps by Mesa Boogie, Cornford, Hughes & Kettner, Marshall’s […]
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 […]
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 […]
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, […]
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 […]
No job too small! This Marshall MG Repair was a simple job – I wouldn’t normally take a lower cost amp in to repair – with the cost of a 2nd hand replacement being around the £50 mark, more than an hours labour and the repair becomes uneconomical for the customer. But this little Marshall […]
Carlsbro Repair – Cobra 80 The owner of this Carlsbro repair complained of an intermittent crackling and occasional dropout. The fault was found to be within the power supply – a not uncommon source of trouble in bass amp repairs. One of the pins on the bridge rectifier had developed a hairline crack through the […]
