Fixing 70's Schwinn seatstay braze

[andyreagan]

First, I'd like to thank everyone here for awesome advice as I've been [very] slowly building my first frame. The community that exists here lends credence to the craft that is involved in building a quality bike frame.

As I've been practicing, and putting my first (practice!) frame together, I've been waiting to fix this broken seat stay joint on a frame I'd picked up a few years back as a SS commuter. A friend needs a ride, so I'm going to finally get around to it.

Naively, I could just braze the thing back together, but I have doubts about the longevity of such a fix. I'm curious what you all would do (I think it is worth fixing), and if that involves a new seatstay cap. Here's what I'm talking about:
