Old thread, but i have the maybe the same problem with my DT25 Head.
Highgain Voicings produce a hissing which getting louder if i turn the Mastervolume to a higher position.
In British Crunch Voicings their is a humbling sound which is independent from the mastervolume.
The amp has new valves (setting up from a tech) and nothing changes.
