FCC data for WSBT:

Note that WSBT is only 5 kW and uses 4 towers to produce a directional pattern, to "protect" other stations.
From this data, the Radio-Locator computer calculates the following coverage map for WSBD:

Note that Elkhart is near the edge of the "local" plot, and the signal strength is adversely affected by the null in the directional pattern. I would not expect full closure of your 6E5 indicator on that station.

Well I realize its probably not going to completely close the eye, but I'm sure it would at least partially close it because it is considered a local station.
I'm aware that some stations even though they come in clearly won't necessarily completely close the tuning eye tube as I know for a fact that the 6FG6/EM84 tuning eye tube that's on my Silvertone stereo doesn't always completely close for some of the FM Stations near me even though they come in clearly but it does make the eye react enough though when tuning around on the dial none the less even if the station is an incredibly close by station that you know its working.
I know for a fact that the FM counterpart to AM 1270 WCMR here in Elkhart, which is 105.3 FM WCMR which is the FM Stereo version of AM 1270 doesn't completely close my tuning eye on my Silvertone Stereo, but yet the sister station to WCMR, WFRN 104.7 here in Elkhart (which both stations broadcast out of the same building and use the same towers) does in fact completely close the tuning eye tube on my Silvertone stereo, so does 97.7 FM (a local classic rock station out of South Bend, Indiana on the FM Band) and 92.9 (a local pop/top 40 hits station that is also from South Bend, Indiana) also completely closes the tuning eye on my Silvertone stereo as well as does the local country stations, the local 24 Hour Classical Station out of Berrien Springs, Michigan however, although it comes in clearly on the radio doesn't completely close the the tuning eye tube on the Silvertone, so I'm sure that the station's power does somewhat influence whether or not the tuning eye closes completely or not, but that doesn't mean its necessarily not going to come in at all, or not affect the tuning eye tube to some extent.
I have no idea how the AM Band is on the Silvertone and how the tuning eye tube on it reacts with the AM band as the original built-in loopstick antenna inside the stereo for the AM Band broke off of the chassis when I was working on recapping the unit so the AM Band doesn't work on the Silvertone currently until I can get a new loopstick antenna located for it and installed.
But really though trying to suggest that the stations aren't going to affect the tuning eye tube at all is kind of being a little presumptuous because I would think that a properly aligned tuner and properly working tuning eye tube would react to any sort of station its receiving whether or not its an extremely high powered station or not. If the tuning eye tube isn't responding or barely responding even to the most powerful and closely located stations then it has nothing to do with whether or not the station is extremely powerful or not, it has to do with the fact that something on the radio isn't working right whether the tuner is out of whack or the IFs are out of adjustment and need tweaking or something like that then obviously its probably going to affect whether or not the tuning eye tube is sensitive or not to picking up on signals and responding to them.
I think like OldCoot said more than likely the IF cans are out of adjustment and need to be tweaked back into adjustment again and it will probably fix my unresponsive tuning eye tube issue. Because like I said the tuning eye tube barely responds to even the strongest of stations on the AM Band, ironically though it is completely responsive on the SW band even when there's no audible signal being broadcast it picks up on it and completely closes the tuning eye tube on the SW band which tells me its probably something about the AM Band that isn't adjusted properly (whether it be the IF Cans or the Tuning Capacitor or the antenna adjustments.)
