I'm thinking to buy the TX 11 model , but after studying manuals
I have seen that schematics are related to eu version .
There is a list of mods for US version , but they don't affect tuning step and deemphasys ( ? )
and I'don't understand what they do .
Probably TX 11 is a TX 10 with noise reduction unit added .
TX 11a has AM tuner , but useless because AM ( MW ) is definetively closed here .
Annother idea is to buy the TX1-11 that is the noise reduction unit only .
At present I'm very undecided .
Ciao
