I'm going to say no although a lot depends on your rail voltage. Collector dissipation is the issue @300 mW maximum. On -/+45 volt rails they see around 270 mW dissipation and that changes instantaneously with signal. Worst case they can see instantaneous values of around 500 mW.
The 2SA970 should be OK for the input transistor though.
Are 2SA1208 and 2SC2910 still available, they might be suitable.
What is everyone else who has built this using these days?

It's good for 3.2A. On single die devices, That's pretty much the same as the fuse you're likely to be using. Under normal use you won't pull anything like that. As you say, it isn't difficult to beef those traces up with solid copper wire.@geoffw1,
It’s a good thing I use my amplifiers domestically, not foreign.
I could always add a p2p piece of solid core copper wire to “beef up” the traces.
