As I write this, I'm listening to the whoosh of my DT50-112. I should be hearing less of that, or nothing at all, I believe. And I'm ready to try some new tubes, even though I don't actually need them at the moment.
From what I've seen here in this forum, the EH tubes from the factory are the culprits, but folks trying JJ tubes and other makes have experienced premature failure. There was a post from a Line 6 tech who said that the el84s <EDIT--he did not cite EL84s, I believe he was speaking only of EL34s, which go only in the DT50> MUST be the EH tubes due to narrow tolerances required by Bogner's design, and that EH was the only tube known to be in compliance with the stricter standards. <EDIT see below for the link to this quote>
Further confusing to me is the lack of discussion about the EH tube choices in the el84. <EDIT--SHOULD BE EL34 FOR THE DT50> If you look at MF or Amazon, you'll see that they come in 3 flavors: soft, medium, and hard. Which ones do the DTs ship with from the factory?
One poster opined that replacing the inverter tube and the other little guy (12ax7s if memory serves) helped with the noise floor. Does anyone else concur with this? Apparently any ole 12ax7 will work for these. Should I stick with EH or is another brand better?
So what do you, oh community of DT players, have to say? Care to share?
THANKS!
