I'm sorry to see Norm close, too. But for those who wonder about how you can be a victim of success, just ask my wife. She hasn't seen me for a couple of months. After my "real" job, I head into the shop and come out to eat and go to bed.
I can't speak for Norm, but if I had to guess, I'd say that he didn't go for hiring someone or having his amps built by contract because there's a certain sense of satisfaction in building something yourself, in knowing that you're sort of a craftsman, so that when you send that amplifier out the door, it's like sending a little bit of yourself along with it. Not only that, but Norm was doing it at prices that made his amplifiers affordable for anybody!
Once you start contracting out the process, you become faced with a whole new can of worms - you stop being a craftsman and start becoming a business manager. For somebody who's in the game because he enjoys the work and the satisfaction of building a fine piece of equipment, that kind of takes the fun out of the equation.
But maybe the most difficult thing to deal with is balancing work and home, particularly if you have a family.
Anyway, my best wishes to Norm for the future, too.
