Currently Being ModeratedNov 22, 2011 5:15 PM (in response to radz108)RE: What are the preamp tube positions in the DT50?
The preamp tubes in the DT50 are Electro Harmonix Low Microphonic "EH" tubes and we recommend using those with the amp as replacements.
As for the white noise, part of it is the way the circuit was designed, part of it is the modeling. The nature of the amp is that it is supposed to be that way. It is not a quiet amp.
