New Cams for our 4 Slide Press
date: June 25, 2026 10:30am tags: restoration, machineryMany months ago, some of our volunteers took the one remaining cam on one of our Mullard Heritage presses and painstakingly measured it out once, twice and then once more for luck before it was put into CAD system and a drawing suitable for a foundry to cast and machined was produced. We then had to find someone with the right skills and supply of materials to do the job. Last week, we took delivery of the cams. Each cam is made of two parts and it has a continuous groove which drives one of the press actions. Another step forward in the restoration of our heritage Mullard 4 slide press.
Farewell to Long Wave from Droitwich
Just down the road from our Tungsten Works factory are the long wave masts of the BBC Droitwich transmitter. Sadly it will be shutting down at the end of this month and the faithful valve transmitters will be decommissioned. If you are in the area on Saturday 27th June then try and pop in for the heritage open day and nose around a great piece of British broadcasting and engineering history.
Brimar launch the ‘Ediswan R-Type’ Valve
Nearly a century after the R-types finished production, Brimar Thermionic Products will launch their first valve, completely designed and manufactured in the UK in April. The R-Type valve was the first triode to be produced and it revolutionised the developing electronic industry worldwide.
Our R-Type is designed to have a performance suitable for all vintage sets and its efficient heater uses around 25% less power putting less stress on ageing components in older equipment. The bright emitter employed in this technology makes the valve look dramatic and its relatively linear performance makes it ideal for use in modern hifi projects that require relatively low amplification levels.
This initial run of Ediswan R-Type valves are available to order NOW at a discounted price. Our special launch edition valves will be numbered and certified to mark this special occasion. All Brimar and Ediswan brand valves are ONLY available through our website – brimaruk.com
