This LabGruppen repair was actually for me! As is often the case with people in this trade, I never quite get round to repairing my own gear because I’m so busy with customer’s work. This LAB1200C power amp died with a spark and blown fuse at a New Year’s Eve gig with Newark soul and […]
This is a JHS pedal repair for a good friend and guitarist who now works in London. It’s a two pedal overdrive. Its a Sweet Tea V2 – sounds great! The pedal had been damaged by the use of the wrong power supply. It was a fairly simple repair to complete. No schematics are available […]
This Blackstar HT100 repair was completed for the co owner of an exciting new Grantham based venture ‘Melody Music Rooms’ in Grantham. Melody music rooms are a rehearsal space, recording facility and teaching space located on Westgate in Grantham . It’s the brainchild of a group of Lincolnshire and Nottinghamshire music teachers who wanted to […]
This is the world’s most popular valve amp , meaning I get a Hot Rod Deluxe Repair quite regularly. The amp has two common faults, which are well documented. The first, and most common is the grey ‘IC’ (Illinois capacitor) electrolytic caps which are prone to failure. Fender use these presumably because they’re the […]
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 […]
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. […]
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 […]
