This Peavey Classic 30 repair was a bit of a nightmare! It arrived with a fairly basic problem – the amp wouldn’t turn on. This was down to a loose screw. It held the mains fuse holder internally. When this came loose, the fuse holder was dangling in mid air and shorted mains directly to […]

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!
This Polytone Minibrute Repair came in from a Lincoln customer with an obnoxious hum problem. This unit is probably form the 1980s The issue was solved by adjusting the output stage bias point and improving the connection between the screw mount power supply capacitors and the power amp stage. The amp is a bit of […]
Another first for Keld Ampworks – the first AMI Jukebox repair. I’ve turned down jukebox repairs in the past because I naively had visions of a 7 foot unit arriving in my rather small workshop! This customer was quick to clarify that the amp unit itself is quite small and transportable from his Lincoln location. […]
Actually, let’s start with a slightly different question… Are valve amps louder than solid state amps? They often are. Take for instance a Marshall MG30 and a Vox AC30 and crank them to the max clean volume. There’s no question at all that the Vox will sound significantly louder. Or take a Fender Blues Junior […]
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 […]
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 […]
