Does anyone have a schematic for a 27k7502 I found an open resistor at r310 and cant make out the colors on it for a replacement. I found the the schematic for k7500 but I am not sure if r310 is the same.
Thanks

But is the schematic the same for the 7500 and 7502?
Thanks

If R310 is open, then D310
could be shorted or a short on the video B+ line
to the neck board. The Video B+ should be high in ohms.
If low then theres a short on the neck board.
It go's to the collectors of the video amp transistors.
If you haven't replaced C310 you should or a cap kit.
