I just got off the phone with Fisher.
The line in the manual "Mono headphones will not work" is not accurate. It should read "Headphones with a mono plug will not work".
Inside the machine, the tip and ring are shorted together and the sleeve is ground. This is a mono output, but a mono plug would short the output. Therefore Ratphones are fine in the usual direction of the cable (stereo end in the machine).
Also the output impedance of the F-75 is 274 ohms. Which happens to be the impedance of Ratphones so you get maximum volume.
So you do not need to go out and purchase stereo headphones or request our stereo version.
