Anyone know of a source for old/obsolete breakers? One of the breakers
in the panel at my parents' house failed. It's a circa-1964 Square D
panel, model QO-8R0, and the breaker is a 15A 120/240 twin/tandem one.

The failure mode is that the breaker in question tripped and cannot be
reset. An electrician confirmed that it needed to be replaced, but
hasn't had much luck finding a suitable replacement locally. There are
no known issues with any of the other breakers.

Bay Breakers/Bay Power seems to be one of the go-to sources for obsolete
breakers, but they haven't responded to a message I sent via their web
contact form.

Anticipating the inevitable recommendation, upgrading to a new panel
isn't in the budget right now.

Thanks to all for the feedback. I realize my description wasn't the
best, so to clarify I've uploaded a couple of pics of the panel to
Flickr. The breaker that failed is the one in the #2 slot.

OK the breaker everyone has linked will work. I thought you were
talking about the "unicorn" tandem 240 breaker.
The 2 operating handles are side by side not inline but it works the
same.
I am surprised your "electrician" didn't know that.

Thanks. I wasn't there when the "electrician" was onsite, and the info I
got was second-hand from my elderly father. They'd never used this guy
before, but he came recommended by my parents' equally elderly
neighbors. Apparently it's time to find someone else that actually knows
what they're doing.
