• Tektronix T935A Oscilloscope Repair needed

    I have a T935A scope that stopped working. There is a little bit of smoke coming from one of the boards which seems like the crt and vertical amplifier board. However, I can seem to get to the board to see what is smoking. How can I get to the board? It looks like the volts/division module can be removed so I can get a better look. Does anyone know how to do this? I do have the manual for the scope.

    thanks,
