You seem to understand what your are talking about. We have a couple of old suppressor boxes that seem to have gone bad. Can you give us any specs and sources for filters and MOVs to replace/upgrade? How are the phone line surge suppressors wired? How good are MOVs really, how long can one expect them to last/ how do you tell they are bad or no longer adequate? I read some time ago, that good surge suppressors use Multi Function Ceramics (MFCs) instead of MOVs, because they do not degrade over time. Is that true? Where do you get MFCs (specs)? Are they wired just the same as MOVs? Answers from you or someone else with an EE background in this area would greatly be appreciated. Wolfgang N.
