Hi Terry,

Sorry this is off topic, but i could not help but notice that in the first 
paper i see you are using doorknob caps.  Did those happen to be made by 
TDK?  Do you remember the park number?  Did it start with UHV?  Becuase i 
have some TDK caps rated at 40KV and 9A RMS at 2nf each.  I wanted to use 
them on an extremely compact coil setup (with a 15kv 40ma tran, id use 4 
caps in parallel for 8nf), but wasnt sure if they were up to it.  Please 
let me know what you know about these caps.

Oh, and i just won a scope on ebay, so soon i may also need to read those 
papers you wrote!

Steve Ward.
