Reader David Solomons has written up some notes describing how he managed to repair the display on his PURE Evoke 2S. Some photos are included.
I've made them into a PDF which can be downloaded here
I hope they help but please note I don't have any other details apart from what is already elsewhere on my website, including links to possible suppliers of displays.
One of life’s annoyances is that the mains lead (power cord) of many trailing power cord extensions often sprouts from the ‘wrong end’ of the plastic housing. Then the extension must be used ‘upside down’ or the mains lead has to be ‘doubled back’ to reach the wall outlet. This post highlights some really neat ideas for mains extensions from Brennenstuhl, including pop-up hidden power sockets and trailing leads that have double-ended cable exits.
These details and photos were kindly supplied by Don McQuistan to share with fellow PURE Evoke 1S users wanting to update their displays.

Whilst trawling through my archives of Practical Electronics magazines – I was compiling some PDFs of the 1970/ 71 PE Gemini amplifier for a reader – I stumbled across an advert for a supplier named Garland Bros. Ltd. who were located in London. Their black and white ad showed an impressive shop storefront, enhanced by signs overhead sporting a shopping list of many of the electronic components that they sold. 'South-east London's leading component store', their ad. exclaimed.
This video documentary is the story of Supermarionation, Gerry Anderson's puppetry behind Thunderbirds and other series, which in the 1960s sparked my interest in technology and instrumentation as a boy. View on Amazon or on DVD.
It also reveals the location of the early Century 21 TV studios on a trading estate in Slough. It's now a tyre depot.
Just around the block (on Leigh Street) was the opening shot location of the BBC TV series with Ricky Gervais, The Office, according to Find that Location. It's since been demolished (opening titles: YouTube).

My item on the old Ambra PC - an early/ mid 1990s Windows PC that was actually an IBM clone made by a subsidiary of IBM themselves - caused some interest recently. My first PC was an Ambra and the 1990s were the happiest of times using one. I had a certain fondness for my Ambra Hurdla 486 which played a major part in my freelance career. If you owned one of these fast and smart-looking PCs then you might be interested in my recently updated article, with Ambra brochures and user comments (including some from Ambra-insiders) in my blog entry Take your mind for a run.
Ambra Hurdla PC Light bulbs based on light-emitting diodes are now universally available, and sales easily outstrip CFLs (compact fluorescent lights). They have virtually replaced halogen lights too, which are gradually being made obsolete. This article offers a few pointers about LED specs - specifically the use of Lumens to describe output in a user-friendly way.
