Occasionally I dip into these to see what the chatter is. I don't normally post things. Almost sorry I looked at this thread, given the pages of less-than-productive banter to a simple question!
Matt5595 - in answer to your original question, yes the Veritas PCB has changed (several years ago), but you can feel free to swap out the old one, since the board mounting and terminal layouts were unchanged. The PCB now includes auto-resetting PTCs instead of glass fuses. No this wasn't a standards-related change (as someone alluded to), it was to make life easier for customers.
James' point below about it being potential easier to replace the entire thing, ousting and all, is valid. His comment about replacing it with another brand, however, is suspect...
As is your later praise of that "equipment" that Honeywell sells!
