I have had the unit up and running for hours, burn-in - HI.
Just powered it down to make the fix for the dead end C9. Thought I
would rotate the cap to the cw line but used a wire jumper.
Not tested with a SR yet, my V6.2 stuff all retired to the bottom of
my toy box. I will give it a try with the new toy, V6.3, when
received and assembled.
Thanks for the info with C9.
