The list below indicates the standard warranty period supplied by each manufacturer along with which products are covered by our free 5 Year extended warranty. In the event of a claim, Peter Tyson provides and administers the extended warranty. This extended warranty is on the same basis and terms as the manufacturer’s original warranty, where possible using the same official service providers, giving you total peace of mind for the extended warranty period. In the event of a claim, please contact Peter Tyson in the first instance. Claims for work done by others won't be accepted unless previously agreed.
Please note: We may run promotions and offer longer warranties than advertised below. These will be detailed on the individual product pages and will also be visible on your order invoice.
Should you wish to contact the manufacturer direct for any reason, we have also provided this information within the associated brand sections.
Any extended warranties offered by Peter Tyson are free. We do not include any form of insurance terms such as accidental damage or loan equipment cover.
Warranties can only be fulfilled to goods purchased and delivered within the UK. In order for us to conduct a Warranty claim for goods taken outside of the UK, the goods will have to be returned at your own expense. Alternatively, you can make the goods available for collection at a UK address. This also applies to goods delivered to shipping companies. Subsequent to a successful warranty claim, goods can only be re-delivered to a UK address.
Free warranties provided for TVs, are provided by the Manufacturer/Supplier, and are bound by their own individual terms and conditions. If you need further clarification, please contact us.
All Peter Tyson Extended Warranties are only valid for the original purchaser and are not transferable.
Sold as an individual plug - please note: plug is crimp only.
A ChordOhmic speaker connector crimping service is now available. Get your plugs fitted foc (as per factory spec) when bought from us with Chord speaker cable. Please call for details.
ChordOhmic silver-plated loudspeaker plugs are designed to bring both the electrical and sonic benefits of silver to speaker cables everywhere. The plugs will be fitted as standard to all new Chord Company speaker cable sets as well as being separately available as a retro-fit upgrade, enabling this revolutionary 4mm connector to improve existing Chord Company cables or any other cable brand for that matter!
For many years we have been using silver-plated copper conductors in our designs. Our silver-plated designs are paired with silver-plated connectors. Using silver in cables can be misunderstood, as many people still associate the use of silver with a bright, overbearing sound characteristic. In our experience, however, this brightness is actually caused by a poor choice of insulation material rather than the silver! The only major exception to this rule has been Chord Company gold-plated (4mm/spade) speaker connectors.
Why not gold?
Although gold is generally perceived to be the best plating material for high-quality connectors, its only major advantage is its total resistance to corrosion (not normally a domestic issue!). In our experience, the customer also associates it with performance and quality due to gold’s high commercial value. Matters are further complicated by the various other plating materials on offer in the hi-fi industry (e.g. rhodium, copper, brass and nickel) with each having wildly differing prices and claimed performance levels.
Science, statistics and misinformation as we see it!
Gold is, in fact, the third most conductive metal available. It is outperformed by both copper (+140% better) and silver (+148% better). Better conductivity means lower resistance and therefore, less signal loss. Less signal loss means increased performance – as expressed by Ohm’s law! Hence the name of our new speaker plugs.
Although pure copper is a good conductor, at room temperature it is susceptible to oxidisation and drastically drops in conductivity when oxidised. Plating the copper can protect it from this process. Plating materials include tin (25% as good as gold), nickel (33% as good as gold) and rhodium (50% as good as gold).
Crucially, silver-plating not only makes sense from an electrical point of view, it gives an audibly superior result during listening tests, when compared with gold plated connectors.
What about tarnish?
It’s a common mistake to think that because silver oxidises it is a poor conductor. The reality is that silver does not oxidise until it reaches 170 C. It does, however, tarnish at room temperature, reacting with sulphur in the air.
Although tarnished silver is not the nicest thing to look at (on ornaments or cutlery), electrically, it is less troublesome.
Tarnish (normally silver sulphide) is a soft and malleable material and can be easily moved aside with very little force. We ensure these forces are present in our speaker plugs and spade connectors. The diagram below illustrates the fact that no matter how smooth a contact looks to the naked eye, it is still quite rough at a microscopic level. There are limited points of actual contact, even under fairly high levels of force. By simply moving a connector in and out of the socket, it is possible to effectively clean the contact points. Ensure all equipment is switched off before doing this simple maintenance procedure.
Plugs will also benefit from a major clean, using a good contact cleaner or enhancer.
