What is up with Audio Research during the pandemic?


I ordered a set of tubes for my ARC Ref 3 line stage on May 4, 2020. So far, no tubes, no tracking number, and no contact initiated by ARC. I did get an email response last week from them saying that they were "... working on getting caught up in the shipping department and have not yet shipped your tubes." This post is not to hassle ARC in the midst of a crisis. My hope is that all there are safe and well. Many "non-essential" businesses are struggling and frankly, I want to do all I can to support them. Music has been a wonderful source of comfort and enjoyment for me, now more than ever. I can wait, but I would feel better if I knew that the ARC folks were doing OK.

ARC has provided me with fantastic customer service over the years. If they have been slow getting your tubes out to you, please be patient. These are difficult times for businesses everywhere.
I think many companies are slow right now. I ordered a marantz integrated two months ago and still on backorder 
I called them today to ask a tech question, but their website says they are closed for a while.  I sent an email; I am hoping to hear back soon re; using balanced-output amp with an SP-6.  We shall see...

Cheers!

@richopp try Randy at Optimal Enchantment in Santa Monica, most years he is the largest ARC dealer in USA - more than likely he can answer your question - and he is a really cool dude :-)
