ARC Ref 75 SE issues?


I'm thinking of getting this amp but on a recent thread about tube amps from January there were quite a number of posts on the reliability of arc amps. Anybody have this amp and can comment on its reliability? I was surprised.

Manleys amps were made the same way. When I had a pair of Neoclassic 250s, a tube took out a resistor. Manley would send you out the resistors with pre-soldered clips on them so you didn’t have to send it in. You took out the old resistor leaving the stems soldered to the board, and clipped on the new resistor.

Worked like a charm. Perhaps ARC does something similar?

I gather from your comment above that ARC customer service is not responsive.  I hope that is not true.  In the past Lenard and Kalvin were just tops.  They have a new guy there now. I've spoken to him once or twice and he seemed ok, … but that was about a year ago.  
Hi guys, i don't want to take the thread off topic but I have a question.  I did have a problem with bad jfets on the left channel and paid 900 to get it fixed. Soundwise all has been well but I now have, after working perfectly for the last year, a slightly dimmed left VU meter. Is there an adjustable pot on board to adjust this or does it need to go back for another service?
