Anyone have the correct resistor values of the Rigol DS2072A front end.

Accidently applied an overvoltage to the channel and it damaged the front end.

When I compare the resistor values with a working channel, it looks like I blew out:
1x 2512 49.9R
1x 0603 62R
1x 0603 82R
1x 0603 68R
(see attached picture - green=good channel, red=where bad channel was different.


Does anyone know the correct values of these resistors?
They are all unmarked and without knowing the circuit it is hard to know if anything else is affecting my measurements.

That is perfect.

I googled my way to that info yesterday, but it had be entered into a wordpress site and the resolution on the schematic was so poor I could not tell capacitors from resistors and it wasn't even obvious the schematics had values.
