Old gear does not automatically need a full restoration the day it comes through the door.
The honest question is what the unit is worth to you, what condition it is actually in, whether it is safe to operate, and whether the parts and labor make sense. A targeted repair may be the right answer. A full restoration may be the right answer. Sometimes the honest answer is to stop powering it on and have it inspected first.
A forum conversation can help identify questions to ask. It cannot replace a bench diagnosis, a safety inspection, or a quote based on the actual unit.
