Hard to answer. ML stuff (from the old days) was terrible. If yours "sounded" good to you, I would check out other pre-amps that have no "sound" and see what you have been missing.
If ML has improved its products (the parts were always good, the reproduction was horrible), then try a rebuild, I guess.
Cheers!
