Two vintage GIRARDIN P40 mono block amplifiers.
broadcast quality.
WORK PERFECTLY WELL.
I used them as monitoring amplifiers
Audio transformer on balanced input.
Sound very warm and  close to tube amplifiers
Were used to amplify JBL 4312 and Elipson 402 plaster speakers 
in the years 1998/99 where they were recovered
