Deutsche Elektronenröhren Manufaktur GmbH proudly presents the latest addition to the tube portfolio: The ER284.
This tube is a molybdenum plate version of our 845.
We named it after the Western Electric 284 which was a molybdenum plate tube and had characteristics very close the the 845.
Like our ER242 is a molybdenum version of the ER211 with the same characteristics, the ER284 has the same parameters as the ER845.
Both the ER242 and ER284 are made with new bases from now on. The bases are black with teflon bottom. In addition all molybdenum plate tubes are wired with solid core silver wire inside the bases.
Here the ER284 besides an ER845:
As with the ER242 the molybdenum shows off an orange glow in operation:
These photos are a bit under exposed so that some detail is visible. The filament is actually brighter.
Like the ER242 the ER284 is made in limited numbers and to order. Expect some waiting time if you order these.
Please send an email to thomas -at- vinylsavor -dot- de or info -at- elrog -dot- com if you are interested in this or any other ELROG tube.
Since this summer the 211 and 845 are shipping in the new style with 'inverted' internal structures compared to the older version.
This was done to reduce the heat generated around the bases which enables the use of the tube in amplifiers with restricted air flow around the bases or which have the tubes mounted such that the bottom half is inside the chassis. As for example David Berning amplifiers.
Here is a testimonial from one of the first customers of our new version ER845:
