You probably aren't aware: I began refurbishing old Macs in 1999. I know the drill about caps. Again, to allow access to the Mac for erasure and software management, the washed motherboard is the procedure short of paying and shipping for a re-cap.
Should an owner/collector choose to do so after familiarizing themselves with their "find", I heartily recommend a re-cap. Just NOT as the first thing. There are other things that must be investigated first. Hard drive condition. Floppy drive condition. RAM content and condition. CRT condition. Case, power board, fan, etc. One can toss a lot of money at a Classic or Vintage Mac to make it like new. Especially at today's asking prices. It's best to see what's necessary before "shotgunning" a refurb.

When they fail, the leak electrolyte onto the logic board causing shorts at best, eating through traces at worst. The only way to truly "fix" these is to remove the old capacitors, thoroughly clean the logic board to remove any leaked electrolyte and then replace the capacitors with new ones. Anything other method is a temporary bandage and should not be considered a "fix". - Dylan -- -- ----- You received this message because you are a member of the Vintage Macs group.
