Time flies! We are celebrating the second anniversary of Deutsche Elektronenröhren Manufaktur GmbH! Two years ago I announced the founding of a new company to take over and continue the production of Elrog vacuum tubes.
Initially we continued the production of the 3 types which the former ELROG Elektronenröhren GmbH & Co KG made, the ER211, ER845 and ER300B. All the tubes received significant changes to solve the issues which the old Elrog tubes had and which caused the company to go bankrupt. This finally led to the 'inverted' style of the 211 and 845 which we announced at our 1st anniversary
Right from the beginning we intended also to broaden the tube portfolio. So we introduced molybdenum versions of the ER211 and ER845, which we named ER242 and ER284.
A rectifier was introduced as well, the ER274B and it's UX4 base variant ER274A.
Here a feedback from a customer who uses the ER274B:
Just want to let you know that my 300B amplifier just took the step to next level :-) Have now adjusted it a little for the 2A filament and installed the ER274B. Initial impressions is wider sound stage and deeper bass. Mid and top was already fantastic after the ER300B upgrade. This is now a killer amp that can compete with the best, in my own opinion at least. I am super happy.
The latest additions are the ER801A, ER50...
...and a completely new type, the ER887 a driver tube for the ER845:
With these latest additions we have a total of 10 different types.
The first batch of ER801A has been shipped to customers. ER50 will be shipped this month. We also provided a sample pair ER801A to the Bartola Valve blog for review. And here a feedback from a customer who uses the ELROG ER801a in a line stage:
I find the ER801’s to be far superior in resolution, speed and tonal presentation, especially the bass. I am sure you know the situation of listening to a familiar piece of music with new equipment and hearting parts of the recording you didn’t know where there at all.
I Would like to thank all our customers for using our tubes and especially thanks to the hard working staff of Deutsche Elektronenröhren Manfaktur GmbH. When we started many believed we would not be able to survive this endeavour. But here we are two years down the road and we will keep going!
