Tektronix Oscilloscope Model 2235 AN/USM-488 Repair and calibration

[jcrubin]

This dual channel 100 MHZ oscilloscope has been broken for over two years and i've finally had the time to go hand over hand to isolate the problem that started after it succumbed to a fire that I reported here several years ago due to a failed across-the-line X capacitor.   This is the beginning of the series.
