It depends, everyone has one's own threshold of where the joy of restoration becomes pain.
I have recently restored 111 which has more tubes but the same physical type chassis.

I had bad field coil on the H speaker, bad volume pot and bad interstage transormer.
All RF coils were good.

It is all doable, but depends on your schedule. Also it seems that H speakers do suffer a lot, and the type of the pot they used (wheel contact) do too, as well as interstage transformers.
So getting another chassis, unless a known working one, is still taking a chance.
