I am now back working on audio repairs after completion of building work at my workshop. At the moment, I am not taking any repairs of home audio equipment or powered (active) PA speakers in order to concentrate on guitar amplifiers and Dynacord mixer repairs. I may offer repairs to some home audio amplifiers in the future but only certain makes and models.
LaLuna Technology is an electronic repair workshop in Hadfield, Derbyshire, UK. It is owned and run by myself, Dan Davenport. I specialise in musician’s amplification repairs, valve (tube) guitar and keyboard amplifiers, mixing desks and vintage synthesizers. Contact me by email or phone with make, model and fault details and I’ll see what I can do.
Hadfield is near Glossop, twelve miles from the centre of Manchester and twenty six miles over the Pennines from Sheffield. Visitors are very welcome but please call first to make sure I will be at the workshop.

Repair Terms
I charge £44 per hour for diagnosis and repair time. I initially operate on a no-fix, no-fee basis for the first half hour of diagnosis. Beyond the first half hour I will ask you if you are willing to pay for further fault finding time. Once I have diagnosed any faults, I will send you an estimate for repairs. If I diagnose a fault and prepare an estimate but you decide not to proceed, I will charge a diagnosis fee of £22.
Common Services
Guitar amplifier repairs and modifications
I can repair most makes and models of guitar and keyboard amplifiers including valve amps.
If you have found details of a particular mod on the net that you would like to have done, just email me some links and I’ll see what I can do.
Valve (tube) testing, replacement and biasing
Loss of power, slow warm up, crackles and pops are all possible possible symptoms of tired valves. A well gigged amp can easily wear out tubes in 6 months. Book it in for a valve test now.
Guitar effects pedal repairs
It is often the foot switches that go on these and they can be replaced quite cheaply.
Mixing Desk Servicing
I have worked on many Dynacord mixers and also Soundcraft, Allen & Heath, Yamaha, Studiomaster and other makes of mixer. Common faults are scratchy and broken faders, dead channels and power supply faults. I have done a lot of work on the Dynacord Powermate series of portable powered desks that seem to be so popular with pub circuit singers and musicians. Please have a look at the Dynacord Repairs page. I don’t repair some budget mixers like Soundlab, Kam, Behringer and Citronic as their service manuals and parts are unobtainable.
Speaker testing and replacement
If your cab isn’t sounding as good as it used to, you may have a damaged driver or faulty wiring. Bring it in for a quick diagnosis. I will diagnose faults on active (powered) speakers and replace drivers but I no longer repair the amplifier modules on them except Mackie Mk1 and Mk2 versions.
PAT safety testing
Get your amps (especially vintage ones) safety tested if you don’t want to risk going to rock heaven in the footsteps of Keith Relf of the Yardbirds. He sadly died from electrocution while playing through an badly earthed guitar amp. Valve amps can use HT supplies in excess of 500 Volts DC which is more than enough to stop your heart! A lot of venues ask to see proof of PAT testing before they let you play. A PAT test on a guitar amp, mains cable and multi way extension including a certificate would only cost you £16 and it may save your life.
