naim audio servicing

Naim Audio Power Amps service options

Please note that our servicing of Naim equipment is NOT endorsed by the manufacturer.

PLEASE ALSO NOTE THAT OUR SERVICE IS FOR SLEEVED VERSIONS OF THE NAP250 AND NOT FOR THE EARLIER BOLTED CASE TYPE - FOR WHICH WE DO NOT OFFER ANY SERVICE

Recapping: NAP250/135

Service Option 1

Taking the NAP250/135 service just a little further, the on board capacitors as well as the main capacitors are replaced by top of the market units and certain resistors, known to degrade slightly over time, are also renewed.

Certain semiconductors are renewed by low noise components to offset the effects of aging and therefore loss of performance. The wiring circuitry is amended for better current flow. All trips are reset to makers standards.

Final bench testing is carried out using a Hewlett Packard HP3582A spectrum analyser and an HP339A / Neutrik TP401 distortion analyser.

Price: £237.00 for the 250
£197.00 each for the 135
Full twelve month parts and labour warranty on the complete amplifier

Service Option 2
 
As above but with the additional, following, refinements: The amplifier circuits are rebuilt using high definition components. Any on-board current limiting components are removed for a cleaner and tighter sound. All internal fixings are renewed by non-ferrous components and main output transistors are reseated using advanced pads. Signal path wiring is upgraded to PTFE insulated co-axial cable.Rectification is now by Schottky diodes and some crucial wiring is changed for high definition cables. Settings are reset to the makers specifications and the stringent Hewlett Packard tests above are applied.

Service Option 3

Having proved to be universally popular over the last five years, the NCC200 modules may be transplanted into your Naim 135 or 250. Using the components and techniques in option 2, the NCC200 modules add the final icing to an already superb cake.

Capable of using all the capabilities of the regulated power supply, the NCC200s perform in an almost liquid, effortless manner whatever the musical programme be it rock, classical or intimately recorded solo performers.

The NCC200 conversion has been equated, by the lucky owners who have it, as akin to the much more expensive NAP300 and we're delighted to hear that this complete revamp of the Naim 250 gives so much pleasure.

Naim Audio HiCap Power Supply Service

A full service removing the aged SLCE and replacing them with factory-fresh Kendeil computer grade capacitors of 22000 microfarad capacity. The input and output Din sockets, well known to suffer from sound-degrading corrosion over extended use, are replaced with brand new Preh units for the ultimate in reliability.

All wiring joints addressed during the work are reflowed with a special silver-loaded solder for that little extra bit of resolution. We renew the input mains socket, fuse holder and install new time delay fuses in case the ravages of time have taken their toll on these vital components.

Using fresh tantalum bead capacitors, renewing all the fixings with stainless components and reseating the output regulators on fresh compound, brings this regarded power unit back to its full potential and at the same time, prolongs its useful life for many more years of carefree enjoyment.

Price: £147 for the full service
