ARC's service center is a profit center.
I have been to the factory, and the service team is large for a company of 80 employees.
The D125, although built around 1989, was touted as a reliability breakthrough, due to the addition of an LED on each tube, indicating a weak one, for replacement before failure. That was the only ARC amp ever made with that feature. Tubes can short at any time, especially near the end of life, with no warning. They later added timers to prevent owners from running tubes to failure.
I repeat: What other tube manufacturer has parts failure when tubes fail? It is poor design, and a lot of ARC customer do not care. Many give up on ARC in the long run. The internet forums are full of those stories!
