Agreed on all counts. I may have mentioned this in another thread (that's what getting old does to you), but I called ARC the other day for some parts for my Dual 75a, which I bought in 1974 or thereabouts. Spoke to Calvin, who couldn't have been nicer. They still support a product they made almost 40 years ago!
I used to deal with Leonard there. Anybody remember him? When i had my SP-10 preamp back in the late 80's- early 90's, he always took my calls. And, they were many.
Good company. Got to meet WZJ once back in the mid-70's. He terrified people, at least at the dealer level.
