ARC Ref 75 SE issues?

" If the amp is not under warranty and blows a resister, you can call ARC customer service."  Try doing it now... 

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?

"did"

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.  

That was about a year ago indeed.  We all miss Leonard and Kalvin.
