NAD 3020 Repair

  • NAD 3020 fixed price repair  (plus 3120,3220 and all i/E/A/B variants) - £14555

As well as repairing any faults on your NAD3020 all common problem areas are checked for and rectified under the basic fixed price repair, in particular all controls (tone, volume, switches etc) are all carefully cleaned and lubricated to return them to a serviceable noise and crackle free condition and treated to deter future deterioration.  For discerning owners this is one of the most comprehensive overhauls offered anywhere and each overhaul usually spans a full day on the workbench  (price includes return carriage to a mainland UK address)



Additional Options:

  • Full replacement of all electrolytics - £185 (includes fixed price repair detailed above)

Uses high quality Nichicon audio grade capacitors from their FG, KW, KA and FW range  

If your NAD makes odd noises on first switching on and even hums slightly it is usually a good

indication that a number of electrolytics have failed in which case this option is recommended. In particular those blue/violet electrolytics used have a very poor tolerance indeed compared to modern replacements.   Restore the sound of your tired old NAD 3020 to one as good as the day it left the factory !





  • Installation of improved speaker terminals

A number of customers have enquired in the past about an alternative to the cheap inadequate spring terminals which this modification solves.  High quality UK manufactured screw terminal binding posts which also take 4mm banana plugs are installed in parallel with the existing terminals. Price is £45 if work is carried out at the same time as any of the above two options or £69 if carried out as a separate task (latter price also includes return carriage to a mainland UK address)




Fixed price repair service for other NAD models:


NAD 3130 - £149 (or £189 with electrolytics replaced)

NAD3240 - £149 (or £209 with Electrolytics replaced)



Above prices also include shippng back to UK Mainland addresses after repair.

Buying Used - NAD 3020   

Expect to pay £50-£140 depending on condition with mint boxed or properly serviced examples at the upper end.


One of the first true budget audiophile amplifiers released in the late 1970's it owed it's affordable price to it's Taiwanese construction and was soon bought by the bucket load with circa 1 million units produced. Even today it's a very impressive amplifier for what you will pay and although it looks cheap it's punchy 20W per channel will not fail to make an impression even if it's appearance fails to!  Anyone who once pulled apart their first transistor radio in the 70's will be immediately familiar with the interior of the NAD as it's PCB looks and still smells exactly like a big Hong Kong made transistor radio of that era! The first models without a speaker power on mute can make a bit of a thump when first switched on so don't be alarmed if yours does the same. Along with a highly capable and much respected discrete phono stage these make a fine alternative to a Cyrus One if you need tone controls and prefer a more conventional sized box. The NAD 3020 has gained a deserved reputation as a sought after classic that still sounds fabulous today.


What goes wrong?

  • Main power switch suffers arcing contacts which eventually go high resistance causing switch failure.

            (usually heard as static through speakers for a few seconds or even a fizzling switch!)

  • Extremely brittle plastic  fascia cracks very easily if not well protected during shipping.

  • Dry solder joints can plague these models and the very first models have pretty untidy internal cabling.

  • Broken RCA input socket connections to pcb.

  • Usual noisy volume/tone controls and selector switches in common with equipment of this age.

  • Electrolytic capacitors will be nearing end of life in well used models which have suffered through poor ventilation
