PT CURRENT LIMITING QUESTION!

Hello all,
I have a big question about potential transformers, but first I will tell 
you my story. My first transformer was one of five oil burner ignitors that 
i paid ten dollars for. I was running my coil with no safety gaps or 
anything. I have since blown every one of the OBITs. All that is probably 
wrong with them is that they need to be depotted, but i don't feel that it 
is worth it. They are now serving as nice heavy boat anchors. I am getting a 
potential transformer on tuesday and i will need a way to limit the current 
flowing to it. The word ballast has also popped up in documents about this 
subject which i have read, and it makes me wonder. Can flourescent lamp 
ballasts be configured to serve as ballasts for PTs? I have also heard 
mention of MOTs being used to limit current to PTs. I don't have any MOTs 
nor is there anywhere local that i can get them, (unless i pay a rediculous 
amount of $$$ for new ones). I do have 312kg of small to medium sized step 
down transformers ranging from 20g to 6kg in weight. Most are 115v - 12v 
transformers from radios and stereos. I have a few really big ones that were 
from a huge, i mean monsterous, vacuume tube oscilloscope.
     I have thought about the similarities between these transformers and 
MOTs. I think that they are built the same but just use different winding 
sizes and guages of wire. Is it possible that i can use these transformers 
to ballast a small Potential Transformer? If so, how would i configure them?
Please help.
