hi, I'm from venezuela, and here do not get that piece.
there is any replacement for the 6N138, or an optional piece?

Sorry about my english

thank you very much.

You can leave 6n138 out if you're not going to use MIDI In.
6n139 can be used instead of 6n138.

dmitri thank you so much.
God bless you
