Hi. First off, let me thank the moderator(s) for allowing me to contribute and to pose questions to this group. 
I have a question that I keep getting conflicting info about from Madame Google and elsewhere. I have a neon sign that says "Rock-N-Roll". Its a rather small sign at about 40 inches long by about 7 inches tall. It is made from half-inch diameter glass tubing. The total length of the tubing is about 175 inches. I purchased this sign recently and it, unfortunately, did not come with a transformer. My qestion is how do I calculate what the voltage rating of the transformer needs to be in order to fire up and power this sign safely and reliably. I understand that a transformer rated at 30ma is preferred, and ideally the transformer should be the electronic type so that it can automatically compensate for what the correct voltage needs to be. Please correct me if I have any of this wrong, so far. I have been told by online sites and by neon repair shops in the Minneapolis MN area that a 10kv supply would be suitable. But then, various online sites tell me that 10kv is too high and will lead to a shortened life and / or a damaged sign. Please help. I cant wait to see this sign lit up!!! Thank you in advance. p.s. ROCK N ROLL!!!!!
