I own an ARC Ref 150SE. I also owned the VS 115 and VS110. What was said above is generally true. If a tube arcs, it often takes out a bias resister. Been there and done that a few times.
That said, if you are handy with a soldering iron, you can replace the bias resister yourself. But even if not, there are many ARC service centers located around the country who could do the fix, even while you wait.
If the amp is not under warranty and blows a resister, you can call ARC customer service. They can send you replacement resisters and even a local electronics repair shop can do the fix. The resister is on top of the circuit board and is easily accessed.
I happen to love my Ref 150SE. So, finger crossed, I have been lucky. No problems. The main power tubes are KT-150s, which are pretty robust.
Bottom line: if you really like the Ref 75SE, do a little homework and find out of there is an ARC service center located nearby or a nearby competent electronics repair shop. Fixing a bias resister is no big deal and does not mandate returning the amp to ARC for repair.
