We revive a strategy of Delves to precondition a spectral calculation using an almost-diagonal Galerkin matrix. We also show that hyperasymptotic singular perturbation theory is a specialization of the Delves-Freeman iteration to a single step with a diagonal Galerkin matrix. We calculate the first
