I had a setup almost exactly like this for a short while very recently - only sold it because I didn't need two rigs and my GK Neos are waaay lighter! Would absolutely have kept it if I could.

The AH250 is a terrific amp - love the sound, and it's VERY LOUD! The 250W rating doesn't do it justice. Big, round sound and the EQ and the tone shaping switches make it extremely versatile. The mid-scoop switch on this amp is to die for.
The ad doesn't say what model the cabs are but the 410 looks like a 1048T - again a great cab. The TE 1048 was one of the earliest 410 models manufactured, and it's a big, heavy tone monster. Handles the low end exceptionally well and is tight, articulate and punchy.
My rig had a 1153T which is a more compact 15" cab than that one in the ad. But IMO there are no duds in the classic TE range.
If you have the chance, grab a bass and drive over for a look and a try out. Take a good size car though - I guarantee you'll be coming back with the rig!
