Jon, I have a very similar setup and got buzzed a few times and
like to find out more on the "bleeder resistors" you mensioned
my system retains power when unpluged for more then 24 hours and
I think this may be the answer to my problem.
What I am looking for is something that will drain power after
shutoff in about an hour or earlier so I can work on it.
Will this bleeder resistor reduce power output during normal
opperation?
What size partno. where to get and how should it be wired up.
Thanks for any info you could provide.
