Let me share another nice example of long-range (long-year) repair and maintenance service in Japan provided by
FOSTEX, a speaker components company.
FOSTEX
T925A metal horn super-tweeter was launched in audio market in April 1994, and it has been keeping good reputation until today. It is amazing Fostex still has
T925A in their product lineup. I purchased a pair of
T925A in 1996, and have been using with great satisfactions over 27 years.
Early December 2021, I contacted with
Fostex Company, with no expectation of positive response though, inquiring the possibility of overhaul maintenance of my
T925As. They very quickly responded;
"We thank you and very proud of your long-year loyalty of T925A. We are very happy to give overhaul maintenance of your T925As!"
My
T925As were hospitalized accordingly at
Fostex service center for a week, and came back to my home in 10 days.
Fostex completely disassemble
T925A, cleaned-up every parts, measured, and replaced some of them, including the inner thin connection wires, with new ones; all with reasonable cost including the shipping. If you would be interested, please refer
here on my project thread for the details.
