Going back to 2017 I bought a dozen EL34s & a pair of 6922s from them & there were no issues. It was a telephone order. Based on that experience, I would probably buy from them again, although, more recently, I bought a dozen EL34s from Jim McShane and it seemed like I was getting more personalized service . . . so given a choice, I would prefer to buy from Jim.
