ELROG ER300B production tubes start to roll in


The first tubes from series production start to come in. I expect shipments of just a few pairs each week during the next month. Since there is already a considerable queue of pre orders, I am not taking any more orders until most of the already pre ordered tubes are delivered.

Further impressions of the tubes will be published soon when I also get some feedback from other listeners. Stay tuned.

Best regards



  1. Hi thomas,

    what is the plate impedance on these tubes? i assume higher than 700?

    1. Hi!

      Yes it is higher. Please wait until I had a sufficient number of tubes for characterisation. Then I will have the final data
