Hi!
Today we are celebrating the 5th anniversary of making ELROG tubes! Deutsche Elektronenröhren Manufaktur GmbH was founded in August 2016.
In these 5 years we expanded the tube portfolio to the 14 types shown above. The latest addition is the ER5U4G at the front.
We started with the three types above, ER211, ER845 and ER300B.
Then we added molybdenum plate versions of the ER211 and ER845 and named them ER242 and ER284.
Later we introduced the ER50 and ER801A triodes.
Of course we also needed rectifiers in the line up. First we introduced the ER274A and ER274B and added the ER5U4G this year.
With the ER887 we demonstrated our capability to develop and produce entirely new tube types. In this case a driver tube for the 845. The ER888 is the same tube with molybdenum plate.
Due to the excellent results with molybdenum as plate material we also introduced such a version of the 300B dubbed ER300B-Mo. My personal tube the TM300B completed the trinity of ELROG 300B tubes.
Those 5 years went by so fast. It still feels like a dream to have a tube production at hand.
Thanks to all our customers who are using ELROG tubes in their amplifiers.
Thanks for all partners and suppliers!
And a special thank you to the staff at Deutsche Elektronenröhren Manufaktur GmbH for the hard work and passion in making vacuum tubes.
Looking forward to the next 5 years of producing ELROG tubes
Best regards
Thomas
