Terra 720 volume pot

[[email protected]]

Does anyone have a bench manual for a Terra 720 (older with white
letters on black background)?
I need to replace the volume potentiometer (combined on/off switch and
volume pot) but the pot in the radio doesn't have a part number on it.
Can someone forward a part number and/or source for parts to me?

Thanks,

Dave N.
