Default Input transformer for Spectra Sonics 101 preamp


The current version of these units state 64db of gain with the same
101 card. Where is the extra gain coming from?

Probably an extra stage of amplification, or if the design allows, a
change of feedback resistors to get more gain from the existing
circuit.
