Congratulations on finding a really great vacuum.  I have a 1521 myself.

You could just replace the broken hose end.  They show up on ebay periodically.

The better thing to do though is replace the entire hose, since the original woven ones are notorious for leaking after awhile when the inner lining breaks down and you lose a lot of suction.  You can find lots of replacement hoses online or from a vacuum repair shop.  I think this one is a good price.

The light bulb in the powernozzle is most likely burned out.  That's an easy thing to find at a hardware store.

I have a 1521 as well, the Grand Marquise version. While I like vacuum cleaners to have their original hoses, I could not agree more with replacing the woven hose on yours. I got a beautiful off-white and blue hose from Aerus-Electrolux and it not only looks perfect with the machine, it's also a great performer.

You can find these hoses on eBay occasionally. For the best match, you'd want to look for the one with the pistol-grip (not the gas-pump handle) and in off-white with dark blue tracing. Here's a photo of mine.

I would LOVE nothing better than to buy Electrolux parts locally. However, it's impossible. There are only a couple of vac shops left in the entire Los Angeles area and none of them carry 'older' Electrolux parts. And by 'older,' I mean older than the Diplomat.......

Charles, what a shame that in all of LA there isn't a shop that carries parts for "older" vacuums.  Maybe you should open a shop!  Luckily we still have a few shops here where I can find some items.
