Re: [TCML] Primary tubing

Bert and Garry,

Thanks for the quick response.  I let out a sigh of relief on this one as I 
bought a roll of 100 feet.  My next coil will be a 12 inch with (2) 15KV 
60ma NSTs, so I might still be ok with the 3/8 inch tubing.  If not I have a 
source for 70 feet of dirty 3/8 water tubing (1/2 inch od) which I could 
clean up and anneal if need be.

Rob
