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.

Elektronenröhren Manufaktur HAS named it after the Western Electric 284 which was a molybdenum plate tube and had characteristics very close the the 845. The ER284 has the same parameters as the Elrog ER845.

Both the ER242 and ER284 are made with new bases from now on in black collar and with teflon bottom. All molybdenum plate tubes are wired with solid core silver wire inside the bases.

As with the ER242 the molybdenum shows off an orange glow in operation:

Like the ER242 the ER284 is made in limited numbers and to order. Expect some waiting time if you order these.
