Indentifying  Tubes  -A  Genuine Mullard ECC83
Lots of people have difficulty indentifying tubes but actually there many features that make the originals unique –example the British Mullard,Dutch Philips and German Telefunken & Valvo tubes
Mullard Ltd  was a vintage British tube factory   from  early 1900s  manufacturing  vacuum tubes for worldwide use.Mullard  had  2 primary plants located in Blackburn and Mitchum England .These  plants codes were embossed on each tube by  the suffix “B” and “R” .The ecc83 with suffix “B”  from the Blackburn factory is being revered as the  holy grail  of the ECC83s .

They perfected the manufacture of audio tubes to the highest level  in terms of  audio performance and reliability .Their tubes  of the 50`s and 60`s are highly sought after by audiophiles worldwide for their unparalled audio performance known for its rich natural harmonics and thick and  detailed midrange.
As for the ECC83 tube there are a few ways to indentify a genuine Mullard
1)”B” suffix followed by the production code acid etched on to the tube glass near the bottom  as below
2)the best performing production units  had the “cold” glow signature .That on power on the filament s will glow brightly for a second  or two.These filament part  were key elements  in the perfect audio tube made by Mullard.The elements were later used in the Philips and Valvo tubes when Mullard was acquired by Philips  Holland.
3)Ribbed Long plates and short plates –the earlier Mullards were the  longplates constructions which is revered.The short plates newer designs were meant to reduce microphonics in high gain circuits.
These has a halo (round) getter at the top  which was placed close to the plates as below.
Pls indentify that your Mullard is genuine  with the above tips  as there  many fake  and rebranded ones out there!.
