I've had to deal with AR service three times in the mid to late 80s. Leonard was the man back then, as he is now. The first time was converting it from 240V to 120V when I emmigrated. Quick turn around time and reasonable charge. The second time was when one channel started to make a rustling sound. With just a phone call, Leonard says 'You probably need to replace V1- a 6DJ8. Which was exactly the problem and exactly the solution. Finally one of the filter caps leaked electrolyte all over the circuit board, essentialy destroying it. In spite of the amp being probably out of warranty, and purchased in a different country, it was fixed FOC, including return freight I believe.
I don't know how service is 25 years later, but if it is only half as good as it was back then, it still adds immeasurable value to any of the AR products.
