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
