Since I wrote about the future of the Elrog tubes, I am often asked if there will be new developments. I am very happy to announce a new Elrog tube type, the ER242C, a replica of the Western Electric 242C.
The 242 was first introduced by Western Electric as 242A with metal plate. It was later replaced by the 242B which had a graphite plate. In it's final release as 242C the plate was metal again using molybdenum and with a maximum plate dissipation increased to 100W.
It is basically a 211 with metal plate and increased plate dissipation. It can be used in any 211 amplifier without changes.
The photos show prototypes of the ER242C. These are without the characteristic black area and don't have any printing on the glass yet. The final version will get the same blackened area and the printing, similar to the 211:
Here a close up to show the different plates:
Molybdenum is very difficult to work with. After many trials we came up with a 4 piece plate structure which is assembled together with screws.
In normal operation the plates glow orange:
The plates are intended to be operated like that.
Here the tubes are working in my 801A/211 mono blocks.
Some close ups to the beautiful orange glow:
Quite a sight to behold!
We will do a first limited production run of about 20 pairs next year In February / March. If you are interested to get a pair, we are starting to accept pre-orders for the ELROG ER242C. Due to the difficult forming and assembly process of the molybdenum plate structure, these tubes will have a 50% price premium over the standard ER211.
Orders from within the European Union will be handled directly be us. Please contact me by email or phone. Contact information can be found under the Impressum link.
If you are in the US or Canada you can buy Elrog tubes and pre-order the ER242C through George Lenz of tubesUSA.
I am happy to announce two new distributors for ELROG tubes:
For China, Hong Kong and Taiwan contact Emmanuel Lebreton.
Robert Lai of Live Acoustics represents Elrog in Singapore.
All other regions will be served directly. If you are interested to represent the Elrog brand in your area, please contact me. I hope to announce more distributors soon.
The sound of the molybdenum plate tubes is beautiful. They improve on the qualities of the ER211 with added ambience and resolution. Of course the subjective sound impression of these can vary between different amplifiers and different people might have different perceptions.
I expect the first batch of ER242C tubes to be reserved very quickly. Depending on demand and feedback from the first users we will occasionally make batches of these and might introduce molybdenum plates also as an option for the ER300B
Stay tuned for more news from the tube factory and for new tube type introductions!
