Hi!
I am trying to get rid of excess noise in my m582, and the behaviours I am experiencing are very weird, to say the least. So I am at a little bit of a loss really.
Backstory: I have 2 m582s, and a total of 3 Um70/M71 capsules, as well as a pair of M94 and M70s.
Here comes the strange part - only ONE of my UM70s plays nice with ONE m582 and is virtually noise free, with all other capsules there is a high background tube noise that makes the signal unusable.
What I know so far: It's not the capsules. Apart from the fact that the M94 were serviced by Thiersch, ALL of the capsules sound fine/normal on my MV692 transistors bodies.
But, it kind of IS the capsules, or at least their connection to the m582 bodies - i have noticed that the working UM70 threads a little further onto the headamp (ca. Half a turn) and the connector pin seems to be ever so slightly thicker then all the others.
Has anybody else experienced this with their m582s? I am pulling my hair out over this, the mics seem completely fine, right voltages inside, tube swap makes no difference etc...
Thanks for the help,
David
