Yes, a Y-OUT is a useful facility, and not very commonplace - or at least, not as commonplace as I'd like. Often, if it exists, it has some peculiarity - such as being for channel 2 only in the case of the Tek 2465 (and no-doubt others in that range). In many cases, it's a factory option (so invariably not present!).
In the case of my Philips PM3295, the Y-OUT signal comes from selected trigger source for the delayed time base. That seems a bit peculiar at first - but then Philips aren't exactly known for following convention. Once you've got used to it, it's very handy indeed.
While most connect a frequency counter to the Y-OUT, I recommend trying a powered loudspeaker. For anything audio related - or power supply - it's amazing how much information you can pick out from the sound. And it saves having to have a working audio stage when working on a radio. On my Telequipment DM63, the only Y-OUT socket comes from one of the vertical plug-ins - the V3 differential plug-in, which is a low bandwidth (but high sensitivity) unit, so it acts like a signal tracer with an amazing dynamic range!
