I tried to find a cross-reference to B1182 transistor which is Q106 on the video board. This is a Germanium transistor in what seems to be a TO-66 case.
There's conflicting references to (2S)B1182 transistors or replacements as Silicon devices or germanium devices. This device is on the video board of the ADM3A. So the video board (not CRT) could be from Ball or Motorola or other suppliers. It would be informative to identify the monitor/video board brand/model. Ideally a schematic of the video board showing the part. also: A dead or good Ge transistor, will have a .2 or .3 volt drop across either junction (emitter base, base collector) with a "diode tester" voltmeter. A Si transistor shows .6 or .7 volt drop. Regards Herb Herbert R.
