I've got two hi-fi tuners that overload on the outdoor long-wire (on
AM, of course). Is there a way to tune, preselect, detune, balun,

It depends on what's overloading the receiver. Are you located close to
a strong AM station? In general, a passive pre-selector should help but
you might need just a frequency 'trap' to reduce the strength of the
offending station. Are you using coax for the antenna lead-in or just a
single wire?
Yeah, I'm close to some 'strong' AM stations. Strong in signal
strength, at least. The worst only runs ~350 watts at night, but there
are several that intrude at points on the dial, w/the outside antenna.
I'm using coax from the tuners, about a hundred feet out to the
antenna, grounded at the house and the outside connection point with
buried 8' copper rods. The grounding kills most of the noise- it's
very quiet on the Yamaha T-1 (could stand a little more signal,
actually). But the Yamaha TX-950 and the Onkyo T-4711 get station
harmonics like crazy.
HiFi AM tuners suck.
