The question is in the title.
When opening my L80T GI ( the european model with woodden grille frame ) for having a look for an upgrade of the network filter to NL80T3 I had a surprise : the C3 capacitor ( according to the N80T schematic ) that should have been a 17 µF is in fact a 13.5 µF ! The other capacitors seem to have the correct values except C7 that I can't check because of a lot of glue on it . I can't unfortunately check the chokes values because of a problem with my choke ( Henry ) meter ...
Were there also different versions of the filter on L80T ?
