[R-390] R-391 Set-up

[Rick Popovich]

Hello All,

 

Time to tap the collective's knowledge and experience again - I am in
the process of setting up my R-391 and PP-629 and need to know what the
other connector marked "Auto Tune" on the back panel of the R-391 is for
? 

 

Am I missing another piece of the pie ? Also, where is the best spot for
me to find a copy of the manual for this receiver ?

 

All information on this set-up is welcome.

 

Tnx
