Orange MK3 AD200

Can anyone tell me the values of R10 and R11? They are burned out and can even make out the colors.. Ive searched the web and haven't located an exact schematic. Thanks!

There are schematics here on this thread but only shows R10 82k resistor, slope resistor on the tone stack. Seems like an odd resistor to have flare up? Nothing shows an R11 anywhere on these schematics.

Now I found an AD200 where the R10 and R11 47k resistors are connected to the cathodes of the power tubes. Looks like a bias balance adjustment circuit or something. That is on the attachment I posted.


Also, what are these resistors connected to in the circuit?

Yes I have found the one u mentioned, that schematic is not correct, however the one you sent does seem correct. R10 and R11 sit directly begins the LED/Fuses fir the faulty tube circuit
