Well i don't know how this amp was working before i started the modifications 
but i pulled the resistor from B- to chassis ground, at an AMPS member 
suggestion, to measure it, it was open!  So i grabbed an new wirewound vitreous 
resistor out of the drawer and put it into place and it now works perfectly and 
i have 11.68v off the divider.

I'm not totally clear on the math here though, so if someone wanted to comment 
here is my remaining question..

I have 10 1M ohm resistors in series, so 10,000,000 ohms, and i have 11.68v off 
the divider.  How do i reverse the math to determine the value of the high 
voltage knowing the output of the divider?  See what i'm saying?  I know what i 
measured before using the HV meter, and i know what i have after the divider, 
just wanted to see if they match up.

I have a level that will work with the board now, but i want to understand it 
better.

Thanks and 73,

Scott KBØNLY
