That's what I suspected. I like your idea of crimping a couple of
lugs on on a radial lead modern electrolytic. Fortunately, the rest
of the capacitors that have bit the dust are axial-lead jobs and not
much of a bother to replace.
I wonder if modern capacitors are better than the old ones in this
respect. After all, they've been engineered to withstand use in
switching power supplies, so working with a 120Hz ripple should be
pretty easy.
I'm with Dwight on the Lambdas being well-built supplies. Huge
heatsinks on this thing, given its ratings.
