Tektronix T 912 Sillyscope

[grimer]

Scope # 2 is apart,and no visible signs of damage. After an hour of cleaning the board interconnect pins,and the switches and controls,there is life in this one.
The controls are still scratchy.Channel one will not pass a signal,and the trace shows "noise",even with no probe attached.
At least progress has been made......Maybe the 3rd will be the charmer......
