Hi,
I'm in the building process of two monoblocks with the IceEdge 1200AS1 modules. This module has an input sensitivity of 5V, so there is a need for an input stage with some gain for my equipment with 2V output, and this stage must be balanced.
PS Audio uses this module too with a tube input stage, using a single 12au7 tube per monoblock. A simple anode follower per phase would not be very good because of the lack of common mode suppression, cathode follower has only unity gain - is my assumption correct that it has to be an LTP stage with gain? What else would be possible with only one tube to pass on an amplified balanced signal to the power module?
Many thanks in advance.
