Added to page 32 of the PDF Manual on TekWiki -

Dennis is correct about the standard 3/4" spacing for dual banana plugs, but on my 575 it is a little difficult to insert the later 576/577 fixtures as the pins on the fixtures seem to be just a bit more than 3/4" apart. Loosening the plastic nuts on the 575 helps but does not allow full insertion. Seems as though this may have been discussed some time ago on this group.
