This is a normal experience in the Acopian Repair Department: one of our customers sent us an old power supply with a note indicating that the supply had been in continuous use for 33 years, but he had recently noticed that the output voltage was low. We found that the capacitors had dried up, replaced them and returned the supply to the customer, who thanked us and said he intends to keep using it. See what other customers say.
We focus on making power supplies that will last a long time. You may find power supplies that cost less than ours, or that are smaller than ours, but you won’t find any that last longer than ours. All too often, low-priced supplies are densely packed, run hot, have short lifetimes and short warranties.
All Acopian metal-cased power products have a 5-year warranty, but you can expect them to last a lot longer.
