Subject: [TCML] Terry Filter Question

Just getting back into coiling after a break since last winter (although I have continued to read the TCML posts).  It's good to be back & I have really missed the constantly nagging ozone-induced cough.  

Anyway, I decided to start by rebuilding my little 9/30 coil & got it working very well.  I then came acrossed a 7500/60 NST for a good price and the new transformer has now replaced the 9/30 NST.  I got the coil working, but haven't wanted to push to it too hard until I wire in a Terry filter.  It seems 7500/60s aren't nearly as abundant as 9/30s.  

I had no problem finding info for buliding a Terry filter for my 15/60 coil, but haven't been able to find filter specs for a 7.5/60.  I think the component values need to be different, particularly the MOVs.  Maybe different for other components too.  I'd appreciate it if one of you could point me in the right direction.  

Thanks,  Dennis Hopkinton MA

PS - it's a static gap coil.
