Hi Shane,

Wow!  Sorry to hear the delayed effects are so serious.

Exactly what damage was done?  Do you have a-fib resulting from poor heart signals from the brain or was there some actual tissue damage to the heart or surrounding areas? At this point in time, do the doctors think the open heart surgery (and other treatments) have a chance of correcting the problems?  


KLC:  Bingo - you spotted it!  The kitty picture is just one of many strange surprises hidden in my rigs ... :-).

Use an "AM Courtesy Filter" to limit transmit audio bandwidth  +-4.5 KHz, +-6.0 KHz or +-8.0 KHz when needed.  Easily done in DSP.

Putting a harmless and even nice surprise inside gear is a time honored thing. Used to do PCBs layout on a team, and one guy always created a cartoon character in some corner.

One thing and I mentioned this on the other reflector that Shane and I both frequent is that RF Parts have these Millen  connectors listed 7KV DC @ 2A!!!!! I think they will be ok to 2~2.5KVDC but I would not push it much farther than that! Especially since his experience!

I ha e t had an ussie with current handling.  I've pushed them to well over 6kv and used in an amp that had the capability to hit 5A peaks.

18 kw out...

And I agree Mike, they should be severely derated IMHO.

This isn't the 40s anymore.  We have better methods of HV transfer.
