Hi Richard,
look the double electrolythics please over C2--C55: you have to change minimum the 10uF/350V than its strong "blowed" up...
In my opinion are tantalums not so bad, but the ~30 years old versions are usualy to chhange for better ones as Rifas epoxy potted capacitors and some mains filters too
Wish to end much fan with your repaired PSU!
