Christian,
There are a copy of different Dolby modules that will fit the avant.
The early Pro-Logic version - 4 Powerlinks, no Sub.
The early Dolby module with 4 Powerlinks and a Sub with 2 Digital Coax as well.
The later Dolby module with 2 Powerlinks (for daisy changing) and a Sub with 2 Digital Coax as well.
It's a 10 minute job if you get the right one for the modle of TV. I'm guessing either of the later Dolby ones will work.
I think I may have a 'spare' one of these somewhere.
Cheers
