Gemakshalve is deze pagina alleen in het Engels geschreven.

This page is written using English language only.

This Pioneer TX-9100 was bought in good shape.

It was decided to do a quick refurbishment, using parts already at hand.

Further comments on this page are rather technical, more or less aimed at technicians, to share experiences. They assume people having documentation at hand, which can be downloaded from the web.

For information about this Pioneer equipment, see this really great Pioneer site of Njord Noatun, as well as the well-known fmtunerinfo site.
