The glass and wire factories and chemical manufacturing plants can clearly be seen. The wire factory was built to produce high-grade tungsten and molybdenum wire used in the construction of tubes.

The Mullard Purchasing Department and How to Freak Out a Security Guard

Glenfiled House, Mullard, Blackburn

The photograph above shows the main entrance to the Mullard Blackburn site and ‘Glenfield House’ – a modern office block that was erected in 1961 for the purchasing and personnel departments. I was quite pleased with the composition of this picture which I cheekily snapped while the site security guard was hovering just a few feet from me on the phone to his boss.

Tube enthusiast: know your tube codes.

Mullard Blackburn ECC83 tube code

My recent visit to the Mullard Blackburn factory got me interested in identifying the origin of the few Mullard tubes I own. The factory, date of manufacture and revision of a particular tube can be determined from a code that was etched into the side of the glass envelope. Looking at the photograph of the Mullard ECC83 it can be seen that the code is written in two lines. The … Read More →

Binson Echorec Repainting

Test panel for Binson Echorec paint job

This photograph shows a test panel paint job for a customer who wanted their Binson Echorec echo-delay machine to be restored to ‘as new’ condition. To achieve this beautiful finish two coats are applied to the bare metal. A metallic silver base coat is applied first and then this is overcoated with a translucent gold. There’s a huge amount of depth to the finish and variability in the gold second … Read More →

Ribble House, Mullard Still Stands Proud

ribble_house_mullard_blackburn

Here’s a photograph of ‘Ribble House’ (named after the river Ribble that flows through Lancashire) situated towards the North-West corner the Mullard Blackburn site. This elegant building, erected in the the late 1950s/early 1960s, still stands bold and optimistic. Ribble House was not a factory but was utilised for administration purposes. If you take a moment and have a discerning eye you’ll see the clean, minimalist styling, eggshell-blue panelling and … Read More →

The Triad Transformer in the Blackbird Tube Preamp

triad_transformers

The Blackbird vacuum tube preamp has a dedicated output especially for direct recording. This output is fully isolated and balanced using a 600Ω miniature Triad output transformer driven by a class AB circuit – just like a real tube amp. This imparts some additional sweetness and harmonic overtones to the Blackbird’s tube circuitry. The tone quality is so natural and pleasing to the ear that speaker emulation often isn’t even … Read More →
