re: relay closure

Hi Paul,
-
I made a post or two on amps about my relay test 
results. Rich was the only one who sent me any 
comments. My notes show the last big hot switch
debate went on circa November 02.
- 
The application was a Research Project (now 
published) which used the 0-7kv power supply 
I built into the old PC computer Tower using 
surplus parts http://sonic.ucdavis.edu/hvps 
(sorry, I'm not in any of the people pics at the 
bottom)
-
I used some very high end scopes to see 
how the various relays preformed using 
speedup circuits and conventional controls. 
- 
I quickly discarded the relays because I could 
not get performance acceptable in my 
opinion based on 3 days worth of testing 
many types of Kilovac and Jennings 
vacuum relays. I burned a few coils out 
in the testing process. 
-
Even though the scopes recorded the 
pronounced bouncing, I did not think to 
save the relay test results. I quickly moved 
on to using fets for the project. 
-
Some posts made to amps result in more 
work than I have or want to make time to 
deal with.  I've still got the relays, high end 
scopes and the circuits. If I have some free 
time, I might go back an re-record the 
results of similar testing. Right now I don't 
have the extra time to spare for the task. 
- 
cheers

Hi Skip
I don't recall on your posts
here or in our phone
conversation your results for
the relays being operated at
normal voltage, I know you'll
set me strait here.
