I purchased tubes from Andy three weeks ago and talked to him yesterday to order more. He was away for about a week on a tube buying trip but other than that I’ve had no trouble getting ahold of him. I’d recommend giving him another call. As others have stated, and is noted on his website, email responses could take weeks. Like his tubes and audio gear Andy is old school and does business via the phone but he’s been my go to guy for tubes for years and is the best IMO. Good luck!
